LONDON, Jan 29 (Reuters) - Britain's top share index was higher in midday trade on Friday, rebounding after a sharp decline in the previous session, with banks and energy stocks taking the lead as investors await U.S. GDP data.
By 1159 GMT, the FTSE 100 <
> index was up 33.56 points, or 0.7 percent, at 5,179.30, having closed 1.4 percent lower on Thursday -- its lowest level since Nov. 6 -- weighed down by mounting concerns about the pace of global recovery."(The index's) gain could easily be eradicated this afternoon," said Howard Wheeldon, strategist at BGC Partners, referring to the possible impact of the U.S. gross domestic product (GDP) data.
Banks added the most points to the index, bouncing back after recent falls, with HSBC <HSBA.L> among the top blue-chip risers, up 2.4 percent, while Barclays <BARC.L>, Standard Chartered <STAN.L> and Lloyds Banking Group <LLOY.L> put on 0.8 to 1.4 percent.
However, Royal Bank of Scotland <RBS.L> missed out on the rally, falling 1.5 percent. A Philadelphia-area real estate developer has sued RBS's Citizens Bank unit, alleging the bank had jeopardized a $700 million project to redevelop a steel-plant site on financing commitments. [
]Energy issues were also in favour, supported by a rise in price of the crude <CLc1> to just above $74 a barrel. Royal Dutch Shell <RDSa.L>, Tullow Oil <TLW.L> and BG Group <BG.L> gained between 0.7 and 1.2 percent.
Miners were also stronger, aided by a positive sector review from Goldman Sachs, which raised target prices across the sector.
Randgold Resources <RRS.L>, Antofagasta <ANTO.L>, Xstrata <XTA.L>, BHP Billiton <BLT.L> and Rio Tinto <RIO.L> added 0.4 to 1.4 percent.
Among individual gainers, Whitbread <WTB.L> topped the FTSE 100 leader board, putting on 2.5 percent as brokers issued positive comments on the leisure group following its recent Investor Day.
International Power <IPR.L> added 1.9 percent as rumours of corporate activity surrounding the group persisted. The power generator recently held abortive talks with France's GDF Suez <GSZ.PA> on a possible asset tie-up.
On the second line, Connaught <CNT.L> was the biggest faller, dropping 8.6 percent after the support services group announced the resignation of Chief Executive Mark Davies.
CAUTION AHEAD OF U.S. GDP
A Reuters survey has predicted that U.S. GDP expanded at a 4.6 percent annual rate, up from 2.2 percent in the third quarter. The data will be released 1330 GMT.
On the domestic front, house prices in Britain rose for a sixth consecutive month in December, increasing by 1.0 percent to bring their total rise since April's low to 9.4 percent, mortgage lender Halifax said on Thursday.
December's rise followed a revised 1.3 percent gain the previous month and means the average property ended the year 5.6 percent higher than they started it. [
