The EU chief negotiator Michel Barnier has said the UK can reverse its position on leaving the single market and customs union up until the end of the Brexit transition period. The EU official gave Theresa May until December 31 2020 to change her mind on Britain exiting the pair as it withdraws from the EU, saying: “So long as they have not left, during the transition period, everything is still possible.”

European Council President Donald Tusk has said Brexit makes him furious, and called on Europe to unite during a speech in Dublin. The statesman warned it would take very little time to demolish the structures of peace and unity built up in the continent.

Facebook has suspended a Canadian data firm that played a key role in the campaign for the UK to leave the EU. The social media giant said AggregateIQ (AIQ) may have improperly received users' data.

Christopher Wylie's specialty was to predict fashion trends before starting work at 17 for a Canadian politician, at 18 he participated in Obama's campaign to learn about his data management and later he helped to found Cambridge Analytica (CA), the consultant accused of misuse of data of about 50 million users of Facebook. However, Wylie said he feels regretful.

The Bank of England signaled on Thursday that it remains on course to lift interest rates in Britain this year and next, as figures showed a yearlong squeeze on consumers caused by a steep fall in the pound appears to be coming to an end.

UK inflation was weaker than expected in February easing some of the squeeze on households' spending power but doing little to change bets on a Bank of England rate rise in May. Official data showed consumer prices rose by an annual 2.7% last month, the weakest increase since July of last year and down from a rise of 3.0% in January.
