London shares bounced back on Tuesday in the wake of some long-awaited upbeat economic data in the Eurozone and positive news for UK banks.The FTSE 100 Index climbed 149.11 points to 6331.83 as Markit's purchasing managers' index (PMI) for euro-area manufacturing rose to 50.8 in December from 50.1 a month earlier, compared to forecasts for a reading of 50.5. A reading above 50 signals expansion.The Eurozone racked up a record trade surplus as the weaker euro made European exports cheaper overseas and higher import prices reduced demand for goods from abroad.Jasper Lawler at CMC Markets said: "European Central Bank policy is bearing some fruit via the Eurozone trade surplus."Europe is an oil importer so the lower oil prices also reduced the cost of one the continent's biggest imports."In the UK, the rate of increase in British house price rises slowed again in October against the previous month, in a further sign that a mortgage clampdown and pressure on incomes have hit the home market.Consumer price inflation in the UK also slowed by much more than expected in November, sending the pound down against the dollar, although sterling staged a comeback later.Meanwhile, crude prices dropped again and the rouble fell against the dollar.In British corporate news, Sainsbury's fell but later recovered to stand 0.1p up at 229.4p after retail research group Kantar Worldpanel said the supermarket's sales fell 1.8% in the 12 weeks to 7 December.
