Britain should mark Brexit by banning the EU flag from being flown on public buildings, Ukip has said.
The blue-starry flag is flying outside Parliament and other public buildings today to mark Europe Day - which celebrates cooperation in the EU.
But Ukip leader Paul Nuttall said the celebration is a waste of money which is as outdated as Empire day.
He compared hoisting the flag in front of public building to singing Beethoven's Ode To Joy - the EU anthem - and called for it to be scrapped when Britain leaves the bloc.
He said: 'Across Parliament square we see the flags of our many of our friends across the continent proudly displayed.
'But it is as relevant as the UK celebrating Empire day.
'That time has passed, and the idea that we in the UK will go out and proudly wave the blue starry flag and sing the Ode to Joy with gusto is laughable.'
He added: 'What isn't laughable is the cost of all this jollity, a cost picked up by the British taxpayer. It is time that the idea of Europe Day be put out to grass.
'From March 31 2019, when Britain leaves the EU for good, that the EU flag, and all it represents be banished from any public building and it becomes treated, as it should, as a form of corporate advertising.'
The EU flag hangs in Parliament Square alongside the national flags of the member states to mark Europe Day
Europe Day marks the early steps towards economic and political integration in Europe .
It commemorates the Schuman Declaration of May 9 1950, when the then French foreign minister Robert Schuman proposed the creation of a European Coal and Steel Community,
Its members agreed to pool coal and steel production under one common high authority.
The declaration states: 'Europe will not be made all at once, or according to a single plan.
'It will be built through concrete achievements which first create a de facto solidarity.'
It was a precursor to the increased political and economic integration which has proceeded over the next 67 years.
