Theresa May is to firmly halt any plans for a second Scottish Independence referendum when she meets Nicola Sturgeon in Glasgow on Monday.
This comes ahead of a key vote in the Scottish Parliament on whether to hold a referendum again.
The vote, postponed due to Wednesday's terror attack in Westminster, is expected to go in favour of a new independence bid, which means Ms Sturgeon will aim to secure a Section 30 order to grant Holyrood the power to hold a referendum.
The Prime Minister is to tell Scotland's First Minister there will be no new referendum before Brexit, amid promises to build a more "united" nation once the UK leaves the European Union.
She will also reportedly make clear Scotland will not get a special deal to ensure its continued access to the European Single Market.
The meeting comes just two days ahead of the formal triggering of Article 50 and the beginning of Brexit negotiations.
