Explainer: Who is 'infiltrating' the Labour party?

The Labour party's "rigorous" vetting process has come under fire, with over 1,200 people being excluded from the vote so far.

Here's a round up of who they are.

Conservatives

Andy Burnham's campaign team have written to Labour's General Secretary expressing concerns over infiltrations by Conservatives.

Conservative MP Tim Loughton was caught signing up as a Labour supporter, but claims he did it to expose the Labour vote "farce".

The party said they had caught 13 people who had previously stood as Conservative candidates signing up to vote.

Other party candidates

It's not just Tories that have been rejected from the vote. The Labour party claims to have caught 214 people who stood as Green candidates at local or other elections.

37 candidates from the Trade Union and Socialist Coalition, a relatively new ultra-left party co-founded by Bob Crow in 2010.

In addition, the Labour party say they have weeded out seven UKIP candidates on the voter list.

'Corbynites'

Jeremy Corbyn has been the surprise success story of the leadership campaign so far.

He's considered such a danger that his own brother, Piers Corbyn, has been barred from voting in the election. Although a member of the Labour party until 2002, he resigned protesting against the privatisation of an estate in London.

He stood as an independent candidate in the last election.

The latest victim of Labour's vetting process is leftwing comedian Jeremy Hardy. He tweeted his experience:

Another comedian and newspaper columnist Mark Steel, who has canvassed forLabour in previous elections, was also rejected with the party saying he did support their values.

Angry bloggers

Jason Cobb was barred from voting after a councillor wrote to the party recommending his removal.

He had written a comment piece criticising his local Labour-run council in 2010.

Its own candidates....

Robert Sharpe, who has stood as a Labour candidate twice and canvassed for other members of his party, was rejected when he signed up to vote.

He was reportedly mistaken for a UKIP voter but following outcry from his fellow local party members, he has now been reinstated.

Ordinary Labour supporters

Many who claim to be lifelong supporters of the party have expressed their shock at being told they were unable to take part in the election.

Pete Sinclair was barred from voter, despite having donated money to the party.

The Labour party has defended the process saying:

"The Labour Party has a robust system to prevent fraudulent or malicious applications.

"All applications to join the Labour Party as a member, affiliate or supporter are verified and those who are identified by our verification team as being candidates, members or supporters of another political party will be denied a vote."
