Government says arrangement will bring in extra £400m on top of more than £15bn of existing annual trade with Korea

The UK has signed a new trade deal with South Korea designed to increase exports of cars, Scottish salmon and Guinness canned in Britain.

Keir Starmer described the deal, which replaces an existing agreement, as “a huge win for British business and working people”. It follows UK deals with India and the US, and the free trade agreement with the EU clinched this year.
