LONDON, April 20 (Reuters) - Britain's top shares rose in midsession trade on Tuesday, led by miners and oils buoyed by commodity prices, and banks were firmer ahead of results from Goldman Sachs <GS.N>.
By 1024 GMT, the FTSE 100 index <
> was up 44.73 points or 0.8 percent at 5,772.64, having closed down 0.3 percent on Monday and down 1.4 percent on Friday.Commodity stocks provided the main support for the index as crude and metal prices rebounded, following falls in the previous session, as appetite for risk returned.
Among the miners, BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Xstrata <XTA.L>, Anglo American <AAL.L> and Kazakhmys <KAZ.L> gained 0.5 to 1.5 percent as base metal prices rose and gold held steady.
Oil majors BP <BP.L>, BG Group <BG.L>, Royal Dutch Shell <RDSa.L> and Cairn Energy <CNE.L> added 0.1 to 1.1 percent as crude <CLc1> rebounded from three-week lows on an increase in jet fuel demand as some airspace across Europe began to re-open, following the chaos caused by a volcanic ash cloud.
But Tullow Oil <TLW.L> topped the UK blue chip <
> fallers' list, off 1.4 percent after the London-based oil explorer said the Dahoma-1 exploration well in Ghana encountered water bearing reservoirs. [The UK's Financial Services Authority caused jitters among investors when it announced a formal probe into Goldman Sachs <GS.N>. [ID:nLDE63J0TP]
However, despite an initial fall back, banks recovered as investors hoped first-quarter numbers from the bank, due at 1100 GMT, would echo strong results from peer Citigroup <C.N.> on Monday.
"The pull back in banks was in part an overreaction to the FSA news and an excuse for some investors to make a quick buck after this morning's gains," said Jimmy Yates, head of equities at CMC Markets.
Royal Bank of Scotland <RBS.L> rose 1.9 percent, also helped by recent bullish broker comments, and peer Lloyds Banking Group <LLOY.L> gained 1.4 percent.
Barclays <BARC.L>, HSBC <HSBA.L>, Standard Chartered <STAN.L> added 0.4 to 0.6 percent.
News that aircraft were beginning to take off around Europe lent support to some travel firms, with Thomas Cook <TCG.L> up 0.6 percent and mid cap easyJet <EZJ.L> 1.6 percent higher, also helped by a JP Morgan upgrade.
But TUI Travel <TT.L>, Europe's biggest travel firm, was down 0.4 percent as it announced plans to raise 500 million pounds ($765.1 million) to fund acquisitions.
