London's blue chip share index raced higher amid hopes of an imminent deal to end America's partial government shutdown and stop the country defaulting on its debt.
Republicans reportedly said a vote on a new plan to end the two-week political deadlock was close as talks ramp up ahead of Thursday's deadline for the US to raise its £10.5 trillion debt limit.
The FTSE 100 Index closed 41.5 points higher, at 6549.1, despite early session losses on Wall Street, with the Dow Jones Industrial Average around 30 points lower after a four-day winning streak.
Optimism over a resolution to the US stalemate also saw further strong gains on the Dax in Germany and France's Cac 40.
IG market analyst David Madden said: "The dark clouds that were hanging over Washington are starting to pass as negotiations between the Democrats and Republicans improve.
"The fear of a US default has left some investors paralysed, but the progress that has been made could pave the way for a deal and that sentiment is driving stocks higher."

Shares declined 8% or 121p to 1464p as the company revealed 17% growth in underlying retail sales in the six months to the end of September.
