The SNP will vote against changes to Sunday trading laws in England and Wales despite being in favour of the position overall.

It argues the bill, which will go before the House of Commons on Wednesday, could lead to pay cuts for employees in Scotland.

Sunday trading is permitted in Scotland but employment rights and protections for workers who choose not to work on Sundays are reserved to the UK Government.

The SNP's economy spokesperson Stewart Hosie MP said the party felt the new bill did not provide adequate provision to ensure workers could not be penalised for not working on Sundays.

He said: "Protecting Scottish workers has been paramount to our decision to oppose the government’s plans on Sunday trading.

"We have had Sunday trading in Scotland for some time and the SNP has never been opposed to it, however, our concerns here are rooted in the knock-on impact to Scottish workers who would be at risk of pay cuts - many of whom are already suffering from George Osborne’s cuts to tax credits and other in work support.

"The SNP welcomed the additional employee protections brought forward by the UK Government which amends the Employment Rights Act to protect any worker from being forced into working on a Sunday, however, they do not go far enough. There is no meaningful means of proactive enforcement of the proposed legislation.

"The SNP are supporters of Sunday trading, we think in principle it can be a good thing, but we are clear that it should not be happening on the back of often low-paid shop workers in Scotland and throughout the UK."

Meanwhile, it has been reported several Conservative backbenchers are planning to revolt against the proposed relaxation of Sunday trading rules.
