"We think that the final decision on Brexit should be given to everyone via people's vote. So today, on the day that Boris Johnson becomes prime minister we are demanding to be heard and asking for a people's vote."

"He better do what he said he would do which is to take us out of the EU on the 31st of October come what may. We did vote for this more than three years ago now. It's ridiculous that it has gone on this long. So, I just want him to honour the commitment that was made."

Pro- and anti-Brexit demonstrators crowded the streets around Parliament on Wednesday as Britain bid farewell to outgoing leader Theresa May and prepared to welcome Boris Johnson as the country's next prime minister.
A double-decker red bus circulated around London with a giant photo of Johnson, reading: #WeAreWatchingYouBoris.
Two giant banners were stretched out in Parliament Square, demanding a people's vote on Brexit.
"Put it to the people," one read in large capital letters which could be read from the skies.
"We think that the final decision on Brexit should be given to everyone," said Kirsty O'Brien, one of the organizers.
Other demonstrators used humour to send their message.
Dressed as a clown and wearing a Johnson mask, one man mocked the incoming prime minister's strategy and famous positivity.
But Brexiteers were equally visible and held large red signs reminding Johnson of the referendum voting results.
Those in favour of Brexit held signs reading "believe in Britain" and "we voted leave."
Pro-Brexit protester Elena Dobson said it was "ridiculous" Brexit had taken this long.
"He better do what he said he would do which is to take us out of the EU on the 31st of October come what may," she said.
