The pound soared against the dollar and euro after the EU and UK agreed a Brexit deal this morning.
Sterling surged 0.9 per cent to $1.29 after Jean-Claude Juncker confirmed that the two sides had reached an agreement after talks went down to the wire. However, the pound later gave up the gains after Boris Johnson's DUP allies quashed his hopes of progress by declaring they will oppose the plan.
Elsewhere, WHSmith agreed a $400m deal to buy US travel retailer Marshall and RBS boosted its Brexit contingency fund to £8.2bn.
It means the retailer now has a further 170 stores in North America, including 59 in airports, with the remaining in busy tourist hotspots including Las Vegas.

The number of UK businesses in significant financial distress has soared 40% in the three years since the EU referendum, according to a report.
Insolvency specialists at Begbies Traynor said 489,000 companies are now in significant distress, with property, construction, retail and the travel sectors suffering hardest - an increase of 22,000 since the same time last year.
It comes at a difficult time for businesses, with many complaining that they are being left in the dark over what happens next in the Brexit process.
Several big-name companies have failed in recent years, including Toys R Us, Carillion and Thomas Cook, with others said to be struggling as big spending decisions are put on hold.
Julie Palmer, partner at Begbies Traynor, said: "With a considerable increase in the number of businesses suffering significant financial distress in the last three years there is growing frustration among businesses that they cannot plan for the future and the whole economy is lagging as a result.
"Much investment is on hold as businesses have their hands tied by not knowing what the state of play will be post-Brexit and whether the agreements or contracts they currently have in place will still be valid following the expected withdrawal, which is contributing to stifled growth nationwide."

Boris Johnson faces an uphill fight to keep his pledge to leave the EU at the end of the month.
Negotiators failed to strike an agreement on Wednesday despite working overtime in Brussels, although leaders still hope to be able to scrutinise a final accord at the summit in the EU capital.
The prime minister could yet be forced into an extension by parliament after EU member states said it was now too late for leaders to formally sign-off the plan in Brussels. If no agreement is in place by Saturday – when parliament will meet for an extraordinary weekend sitting – the prime minister by law has to ask for a delay.
