Nicola Sturgeon has said she will judge whether Scotland's voice is to be heard in the Brexit process before Article 50 is triggered, which is likely to prompt speculation that she could announce plans for a second independence referendum at her party conference in March.

Following talks with Theresa May and the other devolved administrations in Cardiff, the First Minister claimed time was “running out” for a compromise deal.

The Scottish Government is seeking a “differentiated” arrangement that would allow Scotland to remain in the single market after the rest of the UK leaves.

A communique issued following the two-hour talks in Cardiff said the consideration of the SNP’s proposals, and those from Wales, would "intensify" between now and the triggering of Article 50 at the end of March.
