Small groups of protesters held rival demonstrations on Monday as judges inside the Supreme Court in London were hearing arguments as to whether the government had the right to leave Europe without parliamentary approval.

Britain's Supreme Court began hearing a landmark case on Monday that will decide who has the power to trigger the UK's exit from the European Union - the government or Parliament.

The legal battle has major constitutional implications for the balance of power between the legislature and the executive, and has inflamed Britain's already raw wound over how and whether to leave the EU.

Prime Minister Theresa May plans to trigger Article 50 of the EU's key treaty by the end of March, using centuries-old government powers known as royal prerogative.

The powers - traditionally held by the monarch but now used by politicians - enable decisions about joining or leaving international treaties to be made without a parliamentary vote.

British Prime Minister Boris Johnson says he strongly disagrees with the Supreme Court ruling that Parliament's suspension was illegal.

He says the government will respect the decision but indicated he could try to suspend it again.

Johnson said in New York Tuesday that "I strongly disagree with this decision of the Supreme Court" and "I don't think this was the right decision."

He added: "It's perfectly usual to have a Queen's Speech, that's what we want to do."

The Queen's Speech outlines the government's plan for the coming session of Parliament.

Johnson's office meanwhile said he will not resign.

Downing St. said Johnson will fly back from a U.N. General Assembly in New York overnight, earlier than planned.

That will bring him back to London by the time Parliament resumes on Wednesday.

This comes as UK House of Commons Speaker John Bercow welcomed the Supreme Court's ruling that the suspension of Parliament was illegal and said that members are set to resume their work on Wednesday morning.

He said citizens are "entitled" to have Parliament perform its core constitutional duties.

Whitle an anti-government protester outside the court welcomed the ruling and said MP's should go back to Parliament as soon as possible.

"We are in a national crisis right now, and we leave the European Union in just over a month so we need to get back in there and start talking about it because if we don't then we're gonna have some big problems," said Jacob Archbold.

Pro-Brexit demonstrators, meanwhile, chanted slogans of support for Johnson.

But Brexit supporter Michael McFadden also said that Johnson and the Conservatives had "destroyed themselves" and accused former Prime Minister Theresa May of making Brexit backers "look a bunch of fools and we are not a bunch of fools."

The landmark decision immediately prompted calls for Johnson to quit.

I think that the prerogative of prorogation has been used for centuries without this kind of challenge. It's perfectly usual to have a Queen's Speech, that's what we want to do. But more importantly let's be in no doubt, there are a lot of people who want to frustrate Brexit. There are a lot of people who basically want to stop this country coming out of the EU."

In a major blow to Prime Minister Boris Johnson, Britain's highest court ruled Tuesday that his decision to suspend Parliament for five weeks in the crucial countdown to the country's Brexit deadline was illegal.

The unanimous, strongly worded Supreme Court judgment declared the order to suspend Parliament "void and of no effect."

The court found that Johnson acted to limit debate on Britain's impending departure from the European Union in violation of Parliament's constitutional role.

House of Commons Speaker John Bercow welcomed the historic verdict and said Parliament would resume its business Wednesday morning.

There will not be a Prime Minister Questions session in Parliament on Wednesday because Johnson is in New York for the U.N. General Assembly.

An anti-government protester outside the court welcomed the ruling and said MP's should go back to Parliament as soon as possible.

"We are in a national crisis right now, and we leave the European Union in just over a month so we need to get back in there and start talking about it because if we don't then we're gonna have some big problems," said Jacob Archbold.

Pro-Brexit demonstrators, meanwhile, chanted slogans of support for Johnson.

But Brexit supporter Michael McFadden also said that Johnson and the Conservatives had "destroyed themselves" and accused former Prime Minister Theresa May of making Brexit backers "look a bunch of fools and we are not a bunch of fools."

The landmark decision immediately prompted calls for Johnson to quit.

He has not yet commented on the ruling but had said earlier that he would comply with the court's decision.

LEADIN:

US President Donald Trump will pay a state visit to Britain this month as a guest of Queen Elizabeth II.

It will be the latest chapter in the president's relationship with the UK.

STORYLINE:

An oath of office and a promise to the people of the United States to "Make America Great Again".

Donald Trump became the 45th President of the United States, January 2017.

Only a week into his administration, on January 27, Prime Minister Theresa May was the first foreign leader to visit Trump.

A signature welcome, May and Trump got straight to business, holding a joint news conference in the Oval Office in Washington.

Both spoke of mutual cooperation between the two countries and agreed to "lay the groundwork for a UK-US trade agreement."

"I'm convinced that a trade deal between the US and the UK is in the national interest of both countries, and will cement the crucial relationship that exists between us, particularly as the UK leaves the European Union and reaches out to the world," said May.

"I can often tell how I get along with someone very early, and I think we're going to have a fantastic relationship," confirmed Trump.

Hand in hand, the UK-US relations were solidified.

Hours before May's arrival, Trump signed an executive order blocking entry to the UK for citizens from some predominantly Muslim countries.

The order suspended all travel to the US for citizens of Iran, Iraq, Sudan, Somalia, Syria, Yemen.

This erupted worldwide protests and ignited criticism of May's visit to the US.

April 2018 - it was announced that Trump would make a "working" visit to the UK on July 13th.

Taking the form of a giant "Trump Baby", preparations were underway ahead of his arrival.

Protesters organised an unflattering blimp for the president's visit.

July 12, Trump and his wife and first Lady Melania arrived at Stansted.

To greet them that evening, May and her husband Phillip May stood side-by-side at Blenheim palace's grand entrance.

That evening they enjoyed a lavish dinner with guests and owners Jamie Blandford and his wife Edla Griffiths.

While Melania Trump tried her hand at the centuries-old game of bowls while visiting the Royal Hospital Chelsea in London, Trump visited May's country residence, which is 40 miles (65 kilometres) from London.

May welcomed the president to Chequers in Buckinghamshire July 13.

The meeting was expected to be unusually tense after The Sun newspaper published an interview with Trump on Thursday night (July 12).

Trump was quoted as saying he didn't agree with her Brexit plan and backed Boris Johnson to be the next British Prime Minister.

But in front of the cameras, he had nothing but praise for May.

"This incredible woman right here is doing a fantastic job, a great job, and, I mean that. And I must say that I have gotten to know Theresa May much better over the last two days than I've known her over the last year and a half. I mean we've spent more time in the last two days. Yesterday I had breakfast, lunch and dinner with her, then I said 'What are we doing tomorrow?' which is today, 'Oh you're having breakfast and lunch with Theresa May.'"

"The only thing I ask of Theresa is that we make sure we can trade that we don't have any restrictions because we want to trade with the UK and the UK wants to trade with us."

That afternoon, Britain's Queen Elizabeth II welcomed Trump and First Lady Melania Trump to Windsor Castle.

A military band honoured Trump with a royal salute before playing the US national anthem.

The Queen and Trump then inspected the guard of honour before entering the castle where they were scheduled to spend about 30 minutes getting acquainted over a cup of tea.

The palace confirmed plans that Trump will make a state visit to the UK, June 3 2019.

Some of the traditional trappings of an official state visit are likely being scaled back.

Typically one of the highlights is a carriage ride procession that brings the visiting dignitary to the Buckingham Palace grounds escorted by a large number of mounted soldiers from the Household Cavalry as gun salutes are made from nearby Green Park and the Tower of London.

Officials have not said whether that will happen this time, and it may be truncated or eliminated in part due to concerns that a slow-moving procession of horse-drawn carriages could prove an irresistible target for protesters.

The president and first lady are also not going to stay at Buckingham Palace, where state visitors usually lodge, apparently because of renovations that are underway at the 775 room official residence of the Queen.

They are expected to stay at Winfield House, the spacious home of the U.S. ambassador, which has a private garden nearly as spacious as the palace grounds.

The Trumps and their grown children are expected to meet the younger generation of royals, including Prince William, a future king, and his wife Kate, the Duchess of Cambridge.

Prince Harry is also set to meet the Trumps, but his wife Meghan, the Duchess of Sussex, is expected to be at home with their son Archie.

UK Prime Minister Theresa May extended the invitation for a state visit more than two years ago, but the trip has been deferred amid concerns about the president's reception and Britain's extended crisis over Brexit.
