The pound slipped further against the US dollar on Tuesday, lifting blue-chip stocks and pushing the London market towards record territory.
Sterling dropped back below the 1.30 US dollar mark, sinking 0.5% versus the greenback at 1.297.
It came after the American currency climbed following the nation's job openings and labour turnover summary (JOLTS) report reaching a record high.
In a contrast of fortunes, the FTSE 100 Index closed up 10.79 points at 7,542.73, bringing it within a whisker of the all-time record high of 7547.63 recorded on May 26 and June 2.
Top-flight stocks, which report in US dollars or euros, get a boost on the FTSE 100 Index when the pound falls because their earnings benefit from a more favourable currency translation.
Despite slumping against the US dollar, the pound was marginally up against the euro at 1.105.
David Madden, market analyst at CMC Markets, said: "European equity markets had an uneventful morning but the sell-off in the pound and the euro prompted some buying in the afternoon.
"The jump higher in the US dollar, on the back of strong job opening figures, gave a reason for dealers to go long on the greenback, and in turn sell sterling and the single currency."
Across Europe, Germany's Dax was up 0.3% and the Cac 40 in France was 0.2% higher.
On the oil markets, Brent crude rose 0.1% to 52.41 US dollars a barrel amid reports that Saudi Arabia plans to trim oil exports to Asia by 10% come September.
In UK stocks, betting giant Paddy Power Betfair admitted it had been knocked by the lack of a major football tournament and punter-friendly sports results.
The bookmaker, which disclosed on Monday that chief executive Breon Corcoran is to step down after 16 years, reported revenue growth of 9% to £827 million.
Earnings in the six months to June 30 rose 21% to £220 million, but the firm said that, despite strong first-quarter growth helped by favourable Cheltenham results, the following three months were "affected by the absence of a major football tournament and adverse sports results".
Shares were down 310p to 7,240p.
Insurance giant Standard Life also edged lower after it revealed that investors had pulled out £3.7 billion from its funds in the first half.
Shares were off 1.2p at 442.1p after its flagship Global Absolute Return Strategies Fund took a big hit, with net outflows of £5.6 billion.
Despite this, Standard Life notched up a 6% rise in overall pre-tax operating profits to £362 million for the six months to June 30.
