NICOLA STURGEON and David Cameron are expected to clash over the Trade Union Bill in Downing Street today.

Scotland’s First Minister said the Tories’ anti-worker laws are top of her agenda for her meeting with the Prime Minister.

The meeting comes after an attempt by the Scottish government to block the Bill from being enacted north of the border was rejected last week by the Scottish Parliament’s presiding officer.

The decision dealt a blow to unions, who had hoped the Welsh Assembly and local councils in England may also have powers to block parts of the latest Tory assault on organised labour.

But Ms Sturgeon vowed to make clear Scotland’s “clear opposition” to the Bill and tell the Tory PM that any attempt to impose the laws there would be “unacceptable.”

Speaking ahead of the visit, she said: “There is clear opposition across Scottish society and across the Scottish Parliament to this damaging piece of legislation.

“The number of days lost to strike action have been reduced in Scotland by 84 per cent through partnership working, not by slapping sanctions on workers.”

Separately, Mr Cameron was forced to climb down over his plans to ban EU migrants from claiming in-work benefits until they’ve been in Britain for four years.

TUC general secretary Frances O’Grady warned last week his plan would hit a “legal brick wall.”

However the PM is now planning to cut benefits for workers who lose their jobs, limiting the period they can claim from six months to three months.
