Brexit: Boris Johnson makes fresh concession to Tory rebels

Parliament will be asked to override withdrawal agreement only if Northern Ireland protocol is undermined, says PM

Downing Street has clarified that it would ask parliament to support using powers to override parts of the Brexit withdrawal agreement only if the EU undermines the fundamental purpose" of the Northern Ireland protocol.

Boris Johnson brokered a deal with Conservative rebels on Wednesday to see off a potential party revolt, agreeing to grant MPs a vote before invoking powers in the UK internal market bill that would break international law by breaching the EU withdrawal agreement.
