Independence is set to dominate election campaigning in Scotland on Monday as Labour and the Liberal Democrats hit out at SNP plans for a second referendum.

Scottish Labour will launch its General Election manifesto with a key message of opposing a second Scottish independence referendum.

The manifesto will be launched in Edinburgh and promises "never to support" Scotland leaving the United Kingdom, backing up the UK party manifesto unveiled last week by leader Jeremy Corbyn.

In her foreword, Scottish Labour leader Kezia Dugdale wrote: "The SNP has one focus - independence. Labour will campaign tirelessly to ensure that the desire of the majority of Scots to remain part of the UK is respected."

Mr Corbyn added: "Labour is opposed to independence because it would inflict turbo-charged austerity on the Scottish people. We will stand firm in our opposition to a second referendum because we know that together we're stronger and unity is still our strength."

Scottish Labour's manifesto includes promises aimed at creating "transformative change" in Scotland, including moves to outlaw onshore fracking, ensure all primary schools have breakfast clubs and to ban MSPs from holding paid second jobs.

Scottish Liberal Democrat leader Willie Rennie will also use his time on the election campaign trail to hit out at the SNP's plans for a second independence vote.

Speaking ahead of a visit to a gin distillery in North East Fife on Monday, he said: "The SNP's obsession with independence risks pulling us out of both the UK and European single markets. They are giving Scottish businesses the worst of both worlds.

"The SNP need to call off their divisive independence referendum. When the economic challenge to Scottish business is so huge, people will be astonished that the SNP are still risking a barrier for trade with the rest of the UK.

"The Conservatives with their extreme Brexit is hard enough for export businesses already."

Meanwhile, the SNP said their manifesto will include a pledge to protect Scotland's place in the European single market and a call for full devolution of immigration to Holyrood to enable the creation of a bespoke Scottish policy.

Speaking ahead of her party's manifesto launch on Tuesday, leader Nicola Sturgeon said the Conservatives "cannot be trusted to stand up for working families or for Scotland's businesses".

She said: "Only the SNP has a clear plan to boost Scottish jobs, support our businesses, and make work fair for all - and only the SNP can be trusted to stand up for Scotland's interests."

Depute First Minister John Swinney will support Ms Sturgeon on the campaign trail in Perthshire on Monday while Scottish Conservative leader Ruth Davidson will join election candidates in the Borders.

Ms Davidson will highlight her party's plans to support local businesses in the south of Scotland including the creation of a new Borderlands Growth Deal.
