London - Britain's leading share index pushed higher at midday, lifted by gains in heavyweight mining, oils, and banking stocks as recent concerns over the global economy receded while investors awaited US GDP data.
At 1050 GMT, the FTSE 100 was up 25.30 points, or 0.4% at 5 895.44, dipping back just below the psychologically important 5 900 level breached earlier.
Integrated oils and specialty mining were the two best performing blue chip sectors, with Antofagasta a top mining gainer, up 3.1%, supported by a Morgan Stanley upgrade from Wednesday.
Banks also pushed higher led by Lloyds Banking Group, ahead 1.8% as Virgin Money stepped up its bid interest in 600 retail branches which the British bank has been ordered to sell by regulators.
Richard Branson, whose parent company runs the Virgin Money brand, told the Financial Times that he was planning to make a formal bid for the 600 Lloyds branches in July.
Investors were awaiting US preliminary first-quarter GDP, due at 1230 GMT, for fresh direction, with expectations being that the US economy grew at an albeit still sluggish 2.1% annual rate in the first quarter, according to a Reuters survey, rather than the 1.8% pace estimated last month.
"Expectations are for the figure to be upwardly revised, which would certainly help to quell some of the negative sentiment that has been dogging the markets this week," said Ben Critchley, sales trader at IG Index.
"Investors will be hoping that this, along with a sustained rise in commodity prices, can help kick-start another rally in equities - though with the European debt crisis far from resolved, any perceived weakness could see the bears pile back in," Critchley added.
US weekly jobless claims are also due at 1230 GMT.
Man alive
Man Group was the top blue chip gainer, up 4.0%, as the hedge fund group's full-year results beat expectations, with its assets up 3% to $71bn over the past two months.

But on the downside, Burberry Group shed 3.8 percent, retreating after a strong recent run in the share price, after posting full-year results.
"Although the results for YE 31 March were largely in-line with expectations, with tightened margins likely to hurt profitability going forward and the risk of continued slowdown amid fiscal tightening in Asia, H2O Markets believe a period of consolidation is long overdue," says Eku Kobayashi, economist at H2O Markets, which has a "short-term sell" stance on Burberry.
