The UK’s parliament is due to vote tonight on the government’s proposed Brexit deal, with Prime Minister Theresa May claiming she has won material concessions from the EU on the contentious Irish border issue.

But the government’s Attorney General, Geoffrey Cox, published legal advice earlier on March 12 suggesting that Brexiteers’ fears for the deal remain well-founded. Sterling fell sharply on the news, before staging a partial recovery: as of 14:57 GMT the UK currency was worth $1.3125, down 0.2% on yesterday.
