* FTSE rallies 0.4 percent, Wall Street gains help
* Energy, miners rebound with commodities, BP spill report
* Banks weighed by Europe recovery worries

LONDON, Sept 8 (Reuters) - Energy stocks led by BP pushed Britain's top shares higher on Wednesday, outpacing falls in banks which were weighed down by European recovery concerns.
The FTSE 100 closed up 21.92 points, or 0.4 percent, at 5,429.74, after breaking a seven-session winning streak to close down 0.6 percent on Tuesday at 5,407.82.
"The FTSE's pushing up again to the levels it saw four months ago and it's a little bit baffling because if you look at the U.S. and European markets they are nowhere near four-month highs," said David Jones, chief market strategist at IG Index.
Jones said the FTSE's heavy weighting towards commodity-linked stocks has helped with "a bit of exaggeration because of the relatively low volumes but London seems to be particularly resilient at the moment".
BP rose 1.3 percent after a company report shifted much of the blame for the Gulf of Mexico rig blast that led to the United States' worst-ever oil spill on to its contractors Transocean and Halliburton.
Energy and mining stocks helped power the index higher, rallying with commodity prices, although volumes on the FTSE were just 75 percent of its 90-day average.
Rio Tinto added 0.7 percent as a newspaper reported the Anglo-Australian miner is in Russia seeking a possible stake in potash producer Uralkali as competition for the crop nutrient heats up.
