Meanwhile, she said there were signs that a slowdown in the housing market is posing a fresh risk to the recovery.Comments made yesterday by Russian President Vladimir Putin also helped sentiment after he signalled that he is open to discussing measures to resolve the crisis in Ukraine. He also said he had pulled Russian troops from the borders as he called on pro-Russian activists in Eastern Ukraine to postpone a planned referendum this weekend.However, reports suggest that the separatists will not heed Putin's request and the vote will go ahead on May 11th as planned. German Foreign Minister Frank-Walter Steinmeier has been cited as saying that there is "growing momentum amongst a series of separatist groups who neither listen to Moscow, nor to Kiev". He said that growing instability in Ukraine "isn't in Russia's interest in the long term".Barclays, Standard Chartered, BT and WM Morrison riseBarclays gained after unveiling plans to cut 14,000 jobs across the group as part of a strategy update aimed at creating a "leaner, stronger" bank.
