THE SNP have tabled an amendment to Boris Johnson's Brexit deal which would force an Article 50 extension in order to hold a General Election

On Saturday, MPs will have their say on the Prime Minister's Brexit agreement - but a government motion for a simple vote of for or against the deal was rejected in the Commons today.

Ex Tory backbencher Sir Oliver Letwin successfuly led MPs to vote for an amendment on the PM's deal, which would secure a second Brexit referendum if it is passed at the weekend. 

Now, the SNP has tabled an amendment which would see Brexit delayed until January 31 in order for a General Election to take place.

SNP Westminster leader Ian Blackford said: "It is crucial that opposition parties quit dithering, back our amendment, and finally act to bring this appalling Tory government down and stop Brexit.

"Scotland has been completely ignored by Westminster throughout the Brexit process - and our interests have been sidelined. It is clearer than ever that the best future for Scotland is as an equal, independent European nation and the people of Scotland must be given that choice."

The motion, put forward in Blackford's name, instructs the Government to "delete everything from 'that', and insert 'this House declines to approve the withdrawal agreement and future framework; calls for the Prime Minister to secure an extension under Article 50(3) of Treaty of on European Union until at least 31 January 2020 for the purpose of holding an early General Election before the end of the extension period". 

A senior SNP source told the BBC's Nick Eardley that the party will look carefully at any amendment on a second Brexit referendum, but won't do anything to back Johnson's deal.
