Hundreds of people have attended a pro-EU rally to protest against last week's historic referendum result despite the event being officially called off.

Demonstrators chanted "Down with Boris" and "F*** Farage" in protest at two of the leading figures in the Brexit movement, senior Tory Boris Johnson and Ukip leader Nigel Farage.

Thousands of people were expected to attend events in cities across the UK as dissatisfaction with the decision to leave the bloc manifested itself in plans for public demonstrations.

But organisers have been forced to abandon several gatherings over fears about crowd sizes.

The rally in Trafalgar Square had officially been abandoned after 50,000 people declared an interest in attending - but many turned out regardless before moving down Whitehall to continue their protest outside the Houses of Parliament.

Liberal Democrat leader Tim Farron addressed the crowd in Trafalgar Square insisting that the Brexit vote "is reversible".

The Lib Dems have vowed to campaign to take the UK back into the EU.

Mr Farron said: "In politics, as in life, two things are always the case for me: One, if you lose, you have the grace to accept the defeat, but you never, ever, ever give up.

"We as a community must stand together, this is reversible. The people of Britain are decent, outward-looking people. We will carry on direct campaigning."

Heather Gordon, 31, and her friend Jenny Myatt, 32, painted their faces with the EU's gold stars on a blue background and wrapped themselves in flags for the protest.

Speaking outside Parliament Ms Gordon said: "We are here because we have to be here. We are here because our country hasn't really spoken for us."

She joked: "If we had another referendum, it would work in everyone's favour, including my own - because I love tapas."

Ms Myatt said: "I think if you had a referendum today the outcome would be very different."
