LONDON, Aug 14 Britain's top equity index rose on Thursday, bolstered by conciliatory comments from Russian President Vladimir Putin on a visit to Crimea, as well as expectations for a continuation of ultra-loose monetary policy.
TUI Travel led the gainers with a 2.5 percent rise as TUI AG's chief executive said the German company's plans for a merger with the London-listed unit were on track.
Trading volume in the stock was strong, almost twice its 90-day daily average, against just half on the UK benchmark.
The blue-chip FTSE 100 index had risen 29.95 points, or 0.5 percent, to 6,686.63 points by 1441 GMT.
British-listed blue chips extended their gains after Putin, on a visit to Crimea, the Ukrainian region annexed by Russia, said his country would stand up for itself but not at the cost of confrontation with the outside world.
Investors were also betting that the continuation of loose monetary policies will help boost equities.
Weak UK wage data on Wednesday prompted the market to push back its expectations for when the Bank of England would lift interest rates.
Euro zone data released on Thursday was also weak, showing Germany's economy unexpected shrank in the second quarter while France stagnated. That shortened the odds of a move by the European Central Bank to shore up the economy via an asset-purchase programme, which would drive up share prices.
"Clearly Putin's comments have helped in de-escalating the situation (in Ukraine), but as a reaction to the poor economic data we've been seeing - that's turned out to be quite positive for equities," Richard Hunter, head of equities at Hargreaves Lansdown, said.
Property company British Land also notched up good gains, rising 2.3 percent after Bank of America Merrill Lynch raised its rating on the stock to "buy" from "neutral". (Additional reporting by Sudip Kar-Gupta; Editing by Susan Fenton)
