The UK Electoral Commission said it will visit the offices of Nigel Farage's Brexit Party to review how it raises money after former Prime Minister Gordon Brown called for an investigation. The party leads polling ahead of Thursday's European elections as it attracts voters disgruntled at the failure of the mainstream parties to deliver Brexit.
Thousands of Leave supporters gathered outside Parliament to protest against the delay to Brexit, on the day the UK had been due to leave the EU. Traffic was brought to a standstill, amid chants of Brexit now. The March to Leave, which started in Sunderland a fortnight ago, has also arrived in Westminster.
Former UKIP leader Nigel Farage says he is close to backing a second EU referendum to end the whinging and whining of anti-Brexit campaigners. Mr Farage told Channel 5's The Wright Stuff a fresh vote could kill off the Remain campaign for a generation.
British Prime Minister David Cameron was under pressure after his Conservatives were beaten into third place in a key election last March first, by his scandal-hit coalition partners and a Euro-skeptic party.
