The pound strengthened on Friday as investors grew confident that Britain will avoid leaving the European Union without a trade deal.
Sterling was up 0.72% against the US dollar at 1.315 but fell 0.15% versus the euro to 1.153 at the London market close.
The British currency moved higher against the greenback for a fifth straight session, putting it on track for a 1.8% gain across the weak.
Fiona Cincotta, senior market analyst at City Index, said: “Demand for sterling remains elevated as the market becomes more convinced that the UK will avoid crashing out of the EU without a deal.
“Whilst Chancellor Hammond and business leaders mounted pressure on Theresa May to remove the hard Brexit option from the table, the DUP (Democratic Unionist party) also reportedly pledged support to Theresa May’s Brexit Plan B, if there is a clear time limit attached to the Irish backstop.”
She added that pound investors seem “happy to ignore the fact that Brussels are so far not agreeing to a time limit”.
Investors will be looking ahead to another crunch vote in Parliament on Tuesday for Mrs May’s Plan B Brexit deal.
Ms Cincotta doubts whether Mrs May will be able push her deal through as Plan B seems similar to Plan A.

Ms Cincotta said “weak results from Vodafone acted as a drag on the FTSE and miners and oil majors were offering their support”.
