SCOTTISH Liberal Democrat leader Willie Rennie has said that the party would reconsider its policy of unilateral revocation of Article 50, "in hindsight".

Speaking on the BBC's Politics Scotland programme on Sunday, Rennie was quizzed on the strategy, which said an electoral win for the Lib Dems in the December election would see party leader Jo Swinson revoke Article 50 without a second vote.

The Lib Dems also pitched Swinson, who lost her seat in the election to the SNP's Amy Callaghan, as the next prime minister of the country.

During the campaign, the party stepped back from the messages but ended up losing one of its seats in the House of Commons while increasing the party's share of the vote by 4.2%.

Rennie said: "There were some people who believed (the policy was wrong).

"In hindsight, you would take a different approach to the revoke policy, there's no doubt about that.

"What we were very clear about is that we wanted to stop Brexit and that's why we saw an increase in support."

Rennie also claimed the voting system in Westminster hampered his party's chances.

He said: "It's always a battle in general elections to overcome the first past the post voting system.

"The pressure that it puts on our supporters is quite incredible and we didn't manage to withstand that at this election."

The Scottish Lib Dem leader said he and party colleagues were "watching the Labour Party contest very closely" to see if candidates support a change to the voting system.
