Britain's blue chips closed Thursday over 3% higher as traders put recent worries behind them.
FTSE100 finished the afternoon session, up 212 points, or 3.56% to 6,192.

On the losing front, hospitality and hotel giant Whitbread (LON:WTB) was a laggard - dropping 0.44% to stand at 4,799p.
Bolstering sentiment was also news from across the pond of a revision upwards in the second quarter GDP numbers.
As a signal of the strengthening economy, GDP (gross domestic product) rose by 3.7% in the three months to June, which was better than analysts reckoned, and compared with an initial estimate of 2.3%.

Speculation that the US Federal Reserve will hold back from raising interest rates next month also lifted sentiment.

A big riser was Atlantic Coal (LON:ATC), which added 87.50p to stand at 0.15p after it revealed that in the six months to June 30, it delivered sales of US$10.4mln, up 9.7% on the corresponding period a year ago, and an increase in profit from operations of just over US$4.4mln as last year’s small loss turned into a profit of US$4.24mln. The firm was the top London riser.
Fitbug (LON:FITB) added almost 15% as the UK wearable technology expert appointed a new chief executive following the departure of previous chief executive Michael Fried in December.
