1 . SOUNDBITE (English) David Cameron, Britain's Prime Minister:
"If we vote to leave on the 23rd of June we will be voting for higher prices; we will be voting for fewer jobs; we will be voting for lower growth; we will be voting potentially for a recession. That is the last thing that our economy needs after all the difficult decisions that have been made, after all the progress we made in recent years."
2. SOUNDBITE (English) David Cameron, Britain's Prime Minister:
"And I am absolutely convinced that our economic security will be better if we stay in a reformed European Union and it will be seriously at risk if we were to leave. Why do I say that? Because our economy in part depends on being able to trade in the single market of 500 million people across the European Union."
Bristol, England - 14 May 2016
3. SOUNDBITE (English) Boris Johnson, British Member of Parliament for Uxbridge and South Ruislip, and leading campaigner for the Vote Leave campaign:
"Day after day, we are being told by people who should know better that we couldn't hack it (could not succeed outside the EU), that we've got to accept that 60 percent of our laws are now coming from Brussels, which is what is happening at the moment. Sixty percent of laws going through the Palace of Westminster coming from Brussels. That we've got to knuckle under and acquiesce to the European Court of Justice deciding that we can't deport murderers or terrorists. That we've got no choice but to be part of the new arrangements to prop up the euro. Because if the negotiations (on the UK's EU membership terms) have proved one thing absolutely clearly it is that this EU has changed out of all recognition from what we signed up for."
4. SOUNDBITE (English) Boris Johnson, British Member of Parliament for Uxbridge and South Ruislip, and leading campaigner for the Vote Leave campaign:
"And yes, I perfectly accept that this is a David and Goliath fight. This is a struggle of the little platoons against the big battalions. And they have the CBI (Confederation of British Industry) and Goldman Sachs and Peter Mandelson (British Labour party politician, former European trade commissioner) on their side. All the people, all the self-same people who were wrong in the past, by the way. They have them on their side and frankly they're welcome to them as far as I'm concerned."
Britain's Prime Minister on Saturday said that a vote to leave the European Union could tip the British economy back into recession.
Speaking to supporters at a Remain campaign event in his Witney constituency in Oxfordshire, Cameron said economic security in the country would "be seriously at risk" if it votes for Brexit in the upcoming referendum.
However, leading "Brexit" campaigner Boris Johnson on Saturday described the battle between those campaigning for Britain to leave the European Union (EU) and those in favor of remaining as a "David and Goliath" fight.
Speaking at a campaign event in Bristol in favour of Britain leaving the EU, Johnson also said that all attempts to reform the 28-member bloc were "hopeless".
Britons will go to the polls on 23 June for an in-out referendum on the country's EU membership.
