THE pound recovered on Friday after being battered by a week of Brexit developments, while the FTSE 100 was at its highest for almost a month.
Sterling climbed 0.29 per cent against the US dollar to 1.329 and was 0.18% higher on the euro at 1.175.
Fiona Cincotta, senior market analyst at spreadbetter City Index, said: "The pound is finding support from rumours that the DUP could be about to get behind Theresa May's deal in exchange for another hefty sum.
"As (Chancellor Philip) Hammond is drafted in for negotiations, similarities can be drawn to when the DUP agreed to prop up the Government for £1 billion, in 2017. Other Eurosceptic Conservatives ministers are also expected to draw behind the PM's Brexit in fear of the UK never leaving the EU at all."
Meanwhile, the FTSE 100 gained 42.85 points, or 0.6%, to close at 7,228.28. This was the index's highest level for almost a month, coming in just shy of matching the close on February 20.
Michael Hewson, chief market analyst at CMC Markets UK, said it had been helped by "decent performances from oil and gas, house builders and the banking sector" - all of which are exposed to the UK economy.
"It would appear that investors are starting to feed money back into UK equities in the hope that some form of soft Brexit will come about in the coming weeks after the pantomime of this week's political shenanigans at Westminster," he said.
