The London market leapt to its highest level for 18 months today after US unemployment figures eased economic concerns about the world's biggest economy.
The FTSE 100 Index jumped above the psychologically important 5600 barrier - hitting a level not seen since the beginning of September 2008 - several times during the session.
But London's top flight was unable to maintain the mark and ended the day up 1.3% - or 72.6 points at 5599.8.
The Dow Jones Industrial Average was also on the front foot - up 0.8% - in the wake of the jobs figures.
US unemployment held at a rate of 9.7% in February as employers shed 36,000 jobs, fewer than expected.
David Jones, chief market strategist at IG Index, said: "Friday saw UK shares continue the rally that has been in place since early February, but it was the latest US unemployment numbers that really set the markets in motion today."
Meanwhile, the pound also made gains today at $1.51 and €1.10.
London's surge was built on early positive trading after every major market in Asia was higher amid reports that the Bank of Japan may take further steps to protect its economy from deflation.

United Business Media was a key winner in the FTSE 250 after annual profits of £165.1 million easily beat market expectations and as news of a settlement on outstanding tax payments removed uncertainty.
Shares jumped 7%, or 30.6p to 494p, while Informa, a provider of specialist information to the academic and scientific communities, climbed 11.7p to 374.2p.

In the UK, banks, sales departments and IT were kick-starting hiring plans - with Michael Page receiving twice the number of recruitment assignments for banks last month compared with a year earlier.
