This is the BBC.

In this edition of the bottom line, we're talking about how to negotiate a trade deal.

Hello, welcome to the programme.

Now, brace yourselves for the next two to ten years.

We're going to be hearing a lot about trade negotiations.

Most of us have little intimate acquaintance with this protracted and complicated

slice of life. So today, we're going to peek inside that world. What is negotiated in a trade deal?

What happens if there isn't a deal? Why do experts make such heavy weather of the whole thing?

And of course, Brexit. How should Britain be approaching the impending reset of UK trading relations with the EU and the world beyond?

So much to talk about, so little time, just like the whole Article 50 process.

Let me introduce my three guests who know something about trade, international relations and negotiations.

First of all, Janice Charette, who's the Canadian High Commissioner to the UK.

And Janice, you were there, at least for part of the time,

involved in those talks between the EU and Canada on negotiating a trade deal.

We call it CETA.

It doesn't stand for Canada-Europe trade deal. No, it CETA. It stands for, it doesn't stand for Canada, Europe trade deal.

No, it stands for the comprehensive Canada, European Union, economic and trade agreement.

Right. Anyway, we'll call it CETA. It's a trade deal. What was your involvement in that?

Evan, I was working in the Canadian equivalent of the cabinet office for

approximately five years before I came here to the UK as the High Commissioner. And of course,

the cabinet office is responsible for supporting all the cabinet decision-making processes

and advising the Prime Minister on significant issues and initiatives. And of course, the CETA deal was a very big priority for Canada.
