PROTESTERS from Oxford wereamong those who marched through central London on Saturday calling for Britain to remain in the European Union.

After arriving in Parliament Square, the scene of floral tributes for the Westminster terror attack on Wednesday, Unite for Europe campaigners held a minute's silence.

Between 25,000 and 100,000 demonstrators attended the event, calling for Britain to remain in the European Union - just days before Theresa May triggers Article 50 to begin the exit process on March 29.

Oxford for Europe, which organised transport for 100 local people to get there, said: "We are marching to commemorate the historic achievements of the European Union and to urgently communicate to fellow citizens that Brexit is an unfolding national disaster.

"Brexit is not inevitable and Brexit can and must be stopped.

"We are saying that the people have the right to change their mind when facts and circumstances change, when there is new evidence, and when they find they have been deceived.

"The people and their representatives, not the government, must have the final say on any negotiated deal to leave the EU, and one of the options available in this final decision must be the option, if we then choose, to remain in the EU."

Among the marchers were Oxford city and county councillor John Tanner, who with his wife Sue Tanner carried the banner of Oxford Labour Party, and members of Oxford East for Europe, Oxford New Europeans and the Oxford European Movement.

Mr Tanner said: “Leaving Europe could push Oxford’s car industry, university research and hospital staffing off a cliff. Oxford Labour is campaigning for as close links as possible with our European sisters and brothers after Brexit.”

The sunny square was filled with protesters, many draped in the European flag and waving banners aloft, including a number declaring: "We are not afraid".

Another sign read: "I'm 15 I want my future back!"

Liberal Democrat leader Tim Farron addressed the crowd, insisting "democracy continues" and adding: "We stand in defiance of that attack."

Lib Dem former deputy prime minister Nick Clegg, Labour MP David Lammy and Green co-leader Jonathan Bartley were also among those addressing the crowd.

Organisers refused to call off the event after the attack earlier this week, saying in a statement: "We will not be intimidated. We will stand in unity and solidarity.

"We will march on the heart of our democracy and reclaim our streets in honour and respect of those that fell."

The march coincides with the EU's 60th anniversary celebrations in Rome, where leaders of the other 27 member states will gather to discuss plans for the future of the union without the UK.
