A SCOTTISH Labour frontbencher has called for a split from the UK party to reverse its "long-term decline" in Scotland.

Writing in the Daily Record, MSP Monica Lennon said the link with the UK party was stopping the Scottish Labour leadership from being taken seriously.

The shadow health secretary's comments come after the party lost all but one of its MPs in Scotland in last month’s General Election, with Ian Murray re-elected in Edinburgh South.

Throughout the campaign, Labour leader Jeremy Corbyn and Scottish leader Richard Leonard were pressed on their positions on Brexit and Scottish independence, with opponents suggesting contradictions in their stances.

A review is being conducted by Scottish Labour into their election failings, with some in the party having suggested a move towards allowing for a second independence vote.

"With the 2021 Holyrood election looming, the internal review announced by Richard Leonard will rightly examine what went wrong," Lennon wrote in the newspaper.

"We must be honest about our long-term decline. We are the third-largest party at Holyrood but our capacity to shrink is a sure bet, unless we act fast.

"The opportunity to recast ourselves as a modern, dynamic political force is there – if we are prepared to take bold action.

"My submission to the review will recommend we become a separate political party in our own right.

"It's no longer tenable for decisions about Scottish Labour to be taken or undermined by colleagues outside of Scotland.

"The UK link is stopping the Scottish leader from being heard or taken seriously.

"If we look like a pressure group within a UK party structure, we will continue to be rejected."

Last month, Lennon also spoke out in favour of Labour backing a second independence referendum.

Explaining new call for the Scottish branch to split from the Westminster party, Lennon listed reasons including Leonard not being allowed to have his face on the European election leaflets last year, as well as shadow chancellor John McDonnell's comments on Scottish independence at the Edinburgh Festival fringe as examples of the party being undermined.

And she also said that disciplinary issues – including those concerning a councillor who allegedly directed racist comments towards Justice Secretary Humza Yousaf, as well as the suspension of councillors in Aberdeen who were suspended after forming a pact with the Tories – as further reasons why the party should split.

Lennon added: "Scottish Labour needs to stand or fall by its own decisions.

"We either continue at the mercy of the UK party's distant structures or we become a party in our own right."
