"We think Labour should table a confidence motion. And I said last week if it does so, the SNP [the Scottish National Party] would support that. I think it is possible that a confidence motion right now could succeed. This is a government that is weak and unstable and becoming more weak and unstable with every day that passes," Sturgeon told Sky News.
According to the minister, even if the vote failed, it would "help clarify Labour's position."
"Labour's position right now is it won't back a second EU referendum until it has tried and failed to trigger a general election, but if it won't try to trigger a general election then we're in this catch-22 position. It seems to me right now that Labour is as much of a barrier to making progress on Brexit as the Tories are," the politician added.
The statement was made after on Monday, UK Prime Minister Theresa May said she was delaying the vote on the Brexit deal in the House of Commons, originally slated for Tuesday, amid lawmakers' concerns over the Irish border backstop. Jeremy Corbyn, the leader of the main UK opposition party, Labour, said the UK government was in disarray and out of control after May said she was delaying the vote on the Brexit deal.
The Brexit deal was agreed by May’s team and EU negotiators in late November after months of negotiations that saw many suggesting a no-deal Brexit would be a possibility.
However, lawmakers from the Labour and other parties, including Tories, have opposed the deal. The UK politicians have been specifically criticizing the provisions on the Northern Irish backstop which stipulate that Northern Ireland and the United Kingdom as a whole will remain inside an EU-UK single customs area in order to avoid a hard border on the island of Ireland.
