The UK Parliament is about to vote on the Government’s plan to trigger the formal process which will end in Britain leaving the EU. There's little doubt MPs will give Prime Minister Theresa May a green light, but much has changed since last June's Brexit referendum.

The influential advocate of Brexit, Conservative MP Dominic Raab tells Hardtalk's Stephen Sackur he is confident Britain has a bright post-Brexit future on the world stage.(Photo: Dominic Raab, UK Conservative MP.
