LONDON, Sept 4 (Reuters) - The UK's top share index drifted higher in late morning trade on Thursday ahead of the Bank of England's interest rate verdict, as gains in commodity stocks and food producer Unilever <ULVR.L> offset weakness in banks.
By 1022 GMT, the FTSE 100 <
> was up 22 points, or 0.4 percent at 5,521.7, reversing some of the previous session's 1.2 percent fall.Energy stocks were in demand after recent battering and after crude prices <CLc1> rose by a dollar to above $110 a barrel.
BP <BP.L> advanced 3.5 percent, also aided by a deal with the Russian oligarch co-owners of TNK-BP venture, ending months of increasingly hostile dispute. [
]Royal Dutch Shell <RDSa.L>, Tullow Oil <TLW.L> and Cairn Energy <CNE.L> put on between 0.1 to 2.7 percent.
BG Group <BG.L> strengthened 4.8 percent with traders citing market talk of bid interest from Exxon Mobil <XOM.N>. BG declined to comment.
Miners also gained, tracking higher metal prices. BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Anglo American <AAL.L>, Xstrata <XTA.L> and Ferrexpo <FXPO.L> rose between 0.9 and 3.2 percent.
Unilever, however, topped the FTSE 100 gainers, rising 6.3 percent as investors cheered the food producer's announcement of appointing Paul Polman, a consumer goods veteran, as its new chief executive. [
]All eyes are on the Bank of England's interest rate decision due at 1100 GMT. Analysts expects the central bank to leave rates unchanged at 5 percent but expectations are rising that a stuttering economy will force it to cut rates before the end of the year.
"It's too early (for a rate cut) with inflation where it is. The sentiment is to keep rates unchanged," said Mark Foulds, head of equity sales at TradIndex.
"As for the market, it is dead on the back of waiting for that decision. I don't see activity picking up this afternoon. It has got a very quiet feel to it."
Britain's economy failed to grow in the second quarter of this year for the first time since the early 1990s and many analysts believe the country has already tipped into recession.
A survey showed on Thursday British house prices fell for the seventh month running in August to stand a record 12.7 percent lower than a year earlier.
BANKS WEIGH

Sterling, meanwhile, hit a record low versus euro.
British Airways <BAY.L> dropped 3.2 percent to top the FTSE 100 losers, with a struggling pound and a rise in the price of crude denting sentiment. Cruise operator Carnival <CCL.L> also fell 2.2 percent.
Shares in Marks & Spencer <MKS.L> shed 2 percent on newspaper reports that the GMB union plans to launch a series of protests against the retailer after it sacked a member of staff for gross misconduct on Wednesday.
Also featured on the downside, Smiths Group <SMIN.L> lost 2.2 percent after JPMorgan cut its rating for the engineer to "underperform" from "neutral".
Invensys <ISYS.L> added 1.4 percent after JPMorgan upgraded its rating to "neutral" from "underweight" in the same review of the European capital goods sector. (Additional reporting by Jon Hopkins; Editing by Jon Loades-Carter)
