• The government will not need to pass legislation in order to revoke Article 50 if the European Court of Justice (ECJ) confirm an initial opinion reached earlier today in Luxembourg, according to Sky sources.
• The Wightman case - referred by the Court of Session, the highest court in Scotland - was heard by the ECJ last week and one of its top legal officers - the advocate general Campos Sanchez-Bordona - has announced that the UK has the right to withdraw the clause and stay in the EU before its planned departure on 29 March.
• Sky News understands from senior government sources that - in pure legal terms - no legislation needs to be passed

the BBC reported on similar earlier (overnight):

• The UK should be able to unilaterally cancel its withdrawal from the EU, according to a top European law officer.The non-binding opinion was delivered by an advocate general of the European Court of Justice.

Sky report is an opinion on what the court might say. I haven't aven't seen a date specified for when the ECJ might make a ruling.

GBP little changed.
