LONDON, Sept 16 (Reuters) - Britain's FTSE 100 <
> gained 1.4 percent by midday on Wednesday, breaching the 5,100 level for the first time in 12 months, as confidence on the global economy lifted commodity stocks and banks.At 1124 GMT, the FTSE 100 <
> index was 71.95 points higher at 5,114.08. The benchmark index closed 0.5 percent points higher on Tuesday, marking its third straight session of gains.London's blue chips have rallied 20 percent this quarter, on track to post its best such gains since the index was launched in 1984, but was still down around 7 percent from a year ago prior to the collapse of Lehman Brothers.
Banks added most points, fuelled by hopes that the global recession is over and ahead of closely watched U.S. inflation numbers, with August CPI scheduled for release at 1230 GMT.
Barclays <BARC.L>, Lloyds Banking Group <LLOY.L>, Royal Bank of Scotland <RBS.L>, and HSBC <HSBA.L> rose 1.8 to 4 percent.
The European Commission may force Lloyds Banking Group <LLOY.L> to sell all or part of its key Halifax subsidiary in compensation for the billions of pounds of state aid the group has received, the London Times reported. [
]Investors shrugged off data that showed Britain's jobless rate climbed to its highest level in almost 13 years in July. [
]"My general feeling is that the market will keep on pushing forward," said Philip Gillett, a trader at IG Index.
He said recent positive comments and some bullish economic data are overriding any fears that the market might be over bought or due a correction.
"Any sign of improvement and we'll continue on an upward trajectory... supporting the bull's view that the pattern will continue," he said
Miners also weighed with support, boosted by firmer metal prices as comments by Federal Reserve chief Ben Bernanke on Tuesday raised hopes for an increase in demand. [
]Xstrata <XTA.L>, Fresnillo <FRES.L>, Eurasian Natural Resources <ENRC.L>, Rio Tinto <RIO.L>, Randgold Resources <RRS.L>, and BHP Billiton <BLT.L> gained 2.8 to 4.7 percent.
