Jeremy Corbyn has suggested he may take legal action to challenge voting rules for the upcoming Labour leadership election.

Currently, members who joined after 12 January will not be able to vote unless they pay a fee of £25. As many people recently joined the party as £3 supporters to back Mr Corbyn, some of his supporters have raised concerns this could unfairly skew the vote against him.

In an interview with the Sunday Mirror, the Labour leader said: “I’m very concerned. We haven’t heard the end of this. A lot of people joined the party in the past six months and will be extremely annoyed.

“They joined because they want to be involved in the party and they’re not being allowed to.There may be a legal move, but nothing has been decided yet. Not by me anyway.”

Angela Eagle and Owen Smith are both launching rival bids to replace Mr Corbyn as Labour leader. The formal period for party MPs to declare support for candidates begins tomorrow.
