Anti-Brexit campaigner Gina Miller could become the next leader of the Liberal Democrats, it has emerged.

The current Lib Dem boss Sir Vince Cable plans to make it easier for non-MPs to become party leader, he will be revealed next week.

And now insiders have reportedly said Mrs Miller, 53, who successfully led the campaign to allow Parliament a vote on Brexit nearly two years ago, is looking to make the most of the proposal.

The businesswoman and mother-of-three is already set to make a major Brexit speech at the Liberal Democrat conference next month.

But one party source told the Sun: ‘Only Gina Miller would think it was a good idea for her to be leader of the Lib Dems.’

In a bid to turn his anti-Brexit party into more of a movement, Sir Vince will declare plans for a huge remodel of party membership rules on September 7.

It would mean non-MPs could run in leadership elections.

Reports of Sir Vince’s much anticipated speech sparked speculation that he is soon set to step down as leader

Yet the rule changes will be seen as a snub to leadership contenders such as Jo Swinson, the deputy leader, Layla Moran and Sir Ed Davey.

Reports of Sir Vince’s much anticipated speech sparked speculation that he is soon set to step down as leader.

Sources reportedly said that the 75-year-old would use his announcement to reveal plans to quit before the next general election scheduled for 2022.

But last night party insiders insisted he is not planning to leave ‘any time soon’.
