WTO chief: Post-Brexit trade 'uncertain'

The World Trade Organisation (WTO) director general, Roberto Azevedo, has said there could be a lot of uncertainty surrounding post-Brexit trade between the UK and other WTO members, if the UK and EU fail to reach an agreement once Article 50 is triggered.

"In two years' time, if the UK and the EU don't have an agreement, there will be a lot of uncertainty about the legal basis on which trade is going to be happening," Mr Azevedo told BBC HARDtalk's Stephen Sackur.

Trade would not have to stop and cease without an agreement, explained Mr Azevedo, but there may be challenges and uncertainty about which tariffs could apply under certain circumstances with certain partners.
