LONDON, Jan 7 (Reuters) - Britain's top share index fell in midday trade on Thursday, pressured by index heavyweight Vodafone <VOD.L> and mining stocks as investors digested the Bank of England's decision to leave interest rates unchanged.
At 1221 GMT, the FTSE 100 index <
> was down 10.55 points, or 0.2 percent, at 5,519.49, slipping back after closing 0.1 percent higher on Wednesday at a fresh 16-month high.The Bank of England (BoE) kept the scale of its asset purchase programme unchanged at 200 billion pounds ($319 billion) and left UK interest rates at 0.5 percent. [
]Sterling was steady against the dollar and euro after the BoE kept its monetary policy steady.
"(It was) very much as expected. The real test will be next month when we have an inflation report and they will have to make a decision on whether or not to extend QE [
]," said Rob Griffiths, strategist at Cazenove.Vodafone was the heaviest drag on the blue-chip index, off 2.2 percent, with downbeat comments from its U.S. mobiles business partner Verizon Communications <VZ.N> one factor hitting the mobile phone giant. [
]Verizon Chief Executive Ivan Seidenberg said on Wednesday Verizon's profit fell more than analysts expected in 2009.
Miners were also under pressure, retreating after gains on Wednesday, with copper prices falling back after touching a 16-month peak as investors fretted over possible tighter monetary policy in China, the world's top metals consumer.
Xstrata <XTA.L>, Antofagasta <ANTO.L> and BHP Billiton <BLT.L> dropped 0.5 to 1.1 percent, while Eurasian Natural Resources <ENRC.L> lost 1.4 percent, hit by a downgrade in rating from Cazenove to "underperform" in a sector review.
Weakness was also seen among banks, with Royal Bank of Scotland <RBS.L>, a big gainer over the past few sessions, off 2.4 percent, while Standard Chartered <STAN.L> and HSBC <HSBA.L> fell 1.6 and 1 percent.
Negative comment from Keefe, Bruyette & Woods weighed, with the broker cutting its rating on the European banking sector to "neutral", citing jitters about central bank QE exit strategies and restrictive banking regulation proposals.
DEFENSIVES LIMIT LOSSES
Gains were seen among defensive stocks, helping to limit the FTSE 100's losses.
Among pharmaceutical stocks, AstraZeneca <AZN.L> rose 1.2 percent after the firm settled a U.S. patent row over Nexium with Israel's Teva Pharmaceuticals <TEVA.TA>, protecting the Anglo-Swedish drugmaker's top-selling heartburn drug from immediate generic competition. [
]Peer GlaxoSmithKline <GSK.L> rose 0.4 percent.
Tobacco issues were higher, with British American Tobacco <BATS.L> up 1 percent, buoyed by a JPMorgan target price hike, and an upgrade to "buy" from Nomura on Wednesday. Imperial Tobacco <IMT.L> also put on 1 percent.
Drinks firms were also in demand, with Diageo <DGE.L> and SABMiller <SAB.L> up 1.2 and 1.1 percent.
Buyers came in for food retailers after J Sainsbury <SBRY.L> delivered a better-than-expected third-quarter trading update. Its shares climbed 2.2 percent. [
]Peers Tesco <TSCO.L> and WM Morrison <MRW.L> gained 0.4 and 2.1 percent, respectively.
Plumbing supplies group Wolseley <WOS.L> was up 2.7 percent, extending Wednesday's advance with a further percent rise boosted by an UBS upgrade to "buy" from "neutral".
With the UK rate decision out of the way, investors will shift their attention across the Atlantic, to Friday's U.S. non-farm payrolls.
The only important U.S. data set for release later in Thursday's session will be the latest weekly jobless claims data. (Editing by Rupert Winchester)
