Jeremy Corbyn: Labour is 'alive and kicking' in Scotland
The party leader will address delegates at the Scottish Labour conference in Dundee.
Jeremy Corbyn will insist Labour is "alive and kicking" and on the cusp of making significant gains in Scotland as he addresses activists in Dundee.
The party's UK leader hopes to rally delegates by declaring "Labour in Scotland is back" in a keynote speech to the Scottish Labour Party conference.
He is expected to argue for the benefits of a "Labour Brexit" to Scotland but, alongside Scottish leader Richard Leonard, will face continued pressure from pro-remain delegates to back permanent single market membership.
Corbyn will say: "This time last year there were more than a few people in the media who had written the Labour Party off. In Scotland we were told that Labour was dying.
"The truth is that we very much are alive and kicking.
"Labour in Scotland is back.
"Led by Richard Leonard - who has already proven to be an excellent leader of Scottish Labour - we are making Labour's voice heard for a radically fairer society."
Corbyn will say Labour, which gained six Scottish seats in the snap general election last year, is "on the cusp" of winning in about 20 more.
'We need a Labour government to take the reins from the free market ideologues who want to use Brexit to sign a race-to-the-bottom trade deal with Trump's America'Jeremy Corbyn
The Islington North MP, who backs a UK-EU customs union but not permanent membership of the EU single market, will say that the Tories' plans for Brexit are in "chaos".
He is expected to say: "At one of the most important times for our country in its history, we have a divided government that has no clear idea of what it's doing, what it wants, or where it's going.
"As Theresa May has now admitted, under her plans for a reckless Tory Brexit the UK risks losing access to European markets.
"Make no mistake about it, reduced access to European markets means fewer economic opportunities for people in the UK.
"This is why we need a Labour government to take the reins from the free market ideologues who want to use Brexit to sign a race-to-the-bottom trade deal with Trump's America and turn the UK into a deregulated offshore tax haven."
Brexit is due to be debated at the three-day conference during an hour-long slot on Sunday morning, with both Mr Corbyn and Mr Leonard facing calls for the party to back permanent single market membership.
An attempt to force a vote on the matter was blocked by party bosses on Thursday.
SNP MSP George Adam said: "Labour remain hopelessly split over Brexit - and Richard Leonard's support for the Tories' extreme Brexit outside the single market will be the elephant in the room.
"That stance is alienating huge numbers of Labour supporters and members across Scotland and the rest of the UK."
