Germany's flagship stock index got a boost after an upwards revision to the country's second quarter growth figures.

Flash estimates at the end of July had shown German GDP growth of 1.5% quarter-on-quarter in the three months to June. Annually, growth had been estimated at 9.2% on a seasonally-adjusted basis.

The North Sea benchmark was quoted at USD70.73 a barrel at the London equities close Tuesday, up from USD68.44 late Monday.
Craig Erlam, senior market analyst at Oanda, said: "Oil prices are making gains once more after a fantastic start to the week...as China reported no new Covid cases. Prices have been crushed in recent weeks as a result of the uncertain growth outlook for the worlds largest crude importer so Monday's news was naturally very bullish."
Shares in oil major BP rallied 1.3% while peer Royal Dutch Shell saw more moderate gains, 'A' and 'B' shares both ending up 0.9%.
An increase in oil prices was unable to stop airlines ascending on Tuesday, with British Airways parent International Consolidated Airlines rising 2.7%, mid-cap easyJet up 5.3% and Irish budget carrier Ryanair up 2.5%.
Monday's news that the US Food & Drug Administration has fully approved the Pfizer-BioNTech Covid vaccine provided travel firms with some optimism.
Approval comes as the ultra-contagious Delta variant pummels the US, with around 80,000 Americans hospitalized with Covid and more than 700 dying every day. The hardest hit regions include southern states Florida, Alabama, Mississippi and Louisiana.
The decision to fully approve it among people aged 16 and up was based on updated data from the drug's clinical trial involving more than 40,000 people, which found the vaccine 91% effective in preventing Covid.
Weighing on the FTSE 100 was J Sainsbury, falling 4.9% as it gave back some of Monday's 15% jump on M&A speculation. Shares surged on Monday following a report from the Sunday Times saying it could be the next UK grocer to be subject of bid interest from the private equity space.
Stocks in New York were muted at the London equities close, with the DJIA up 0.1%, the S&P 500 index up 0.1%, and the Nasdaq Composite up 0.3%.
Traders continue to look ahead to US Federal Reserve Chair Jerome Powell's Friday appearance at the annual Jackson Hole central banking symposium.
"Stock markets may get another helping hand from Jerome Powell this week when he appears at the annual Jackson Hole event. Until recently, this looked the perfect platform to lay the groundwork for a September taper announcement but some concerning economic releases and a surge in delta cases in the US may see the Fed adopt a more cautious stance for now," said Oanda's Erlam.
The dollar continued to soften ahead of Powell's speech.
The pound was quoted at USD1.3721 at the London equities close Tuesday, firm compared to USD1.3717 at the close on Monday. Against the yen, the dollar was trading at JPY109.67, down compared to JPY109.78 late Monday.
