Hello and welcome to a new series of political thinking.

A conversation with, rather than a news interrogation,

of someone who shapes our political thinking,

about what has shaped theirs.

This week, we're in Edinburgh, in particular here at Butte House, the home of Scotland's First Minister.

We're here because it's a very big year for elections. An election here in Scotland where Scots will get to choose who governs them for the next five years.

In Wales, where the people of Wales will make a similar choice, and indeed

millions of people in England choosing who their local councillors are. That of course matters

in and of itself, but it will have a huge impact on who's seen to be up and down in UK politics.

But there's something even more important at stake, perhaps the future of the United Kingdom itself.

First Minister, thank you for joining me on political thing.

The world has changed dramatically in the past few days, in the past year, and really because of one man, and you know Donald

Trump better than most, most British politicians, certainly.

to be very, very focused in your engagement with him.
