Ukip donor Arron Banks plans to bankroll 200 Commons candidates to 'drain the swamp' of Westminster careerists and corruption.

The insurance tycoon, who was with Nigel Farage for the first British meeting with Donald Trump on Saturday, has long planned a 'movement' he hopes will emerge from the Brexit vote.

And Mr Banks now believes there is sufficient anti-establishment feeling across the UK to launch his move against the '200 worst, most corrupt MPs'.

The billionaire told The Times he will support the candidates on a broad platform with few specific policy aims beyond reforming the Westminster system.

Mr Banks plans to make Keith Vaz his first target amid calls for the Labour grandee to quit the justice committee over police investigations into allegations that prompted his resignation from the chairmanship of the home affairs committee in September.

He said: 'You would rate MPs by (undesirability) with Keith Vaz at No 1, and field a great candidate, a military guy, doctor, someone who has done something with their life.

'It would be a one-off attempt to drain the swamp. It would be highly amusing to tease career politicians with a hot poker.'

He added: 'It’s a very simple agenda: to destroy the professional politician. I like the idea of clearing the place out, setting new rules, maybe reducing the number of MPs.

'Not a party from the left or right. Just to clear out the worst lot.'

Mr Banks suggested he could endorse reforms such as two term limits for MPs, abolition of the House of Lords and a minimum age limit of 40.

The funding would initially come from Mr Banks - who gave a £1million to Ukip and spent around £7million on the EU referendum - but he has networks of other donors who contributed to the Brexit cause.

Pressure on Mr Vaz grew over the weekend and Tory MP Andrew Bridgen, who voted against Mr Vaz's appointment two weeks ago, told MailOnline everything he had warned MPs about when the Labour grandee bid for his position on the committee had come to pass.

He said: 'I said matters relating to his resignation from the Home Affairs Committee were not resolved.

'He brings Parliament into further disrepute. He should stand down.

'I'm also calling on Jeremy Corbyn to do the right thing and suspend Keith Vaz from the Labour Party until any police investigation is concluded.'
