* Commodity stocks and banks gains on stronger Wall St
* UK Q1 GDP contracts, sharpest drop since 1979

LONDON, April 24 (Reuters) - Britain's top share index rose 1.2 percent by midday on Friday, shrugging off data showing the UK's first-quarter growth shrinking at its sharpest pace in 30 years, as better U.S. sentiment lifted banks and commodity stocks.
By 1017 GMT, the FTSE 100 <
> was up 49.99 points at 4,068.22, after losing 0.3 percent on Thursday. The UK index is down 8.3 percent this year after sliding more than 31 percent in 2008.Banks gained, boosted by better-than-expected results from several U.S. regional banks. Barclays <BARC.L>, Lloyds Banking Group <LLOY.L> and HSBC <HSBA.L> added 1 to 3.3 percent.
A price target hike from UBS also added to gains in Lloyds.
U.S. stocks rose on Thursday as earnings from big U.S. regional banks, including PNC Financial Services Group Inc <PNC.N> and Fifth Third Bancorp <FITB.O>, provided glimmers of hope for a sector damaged by rising loan losses as the recession persists.
U.S. Treasury Secretary Timothy Geithner, writing in the Financial Times ahead of the meetings of G7 and G20 officials in Washington later in the day, said there were signs of improvement in global markets and the world economy but that the 2009 outlook remained challenging. [
]Britain's economy shrank at its sharpest rate since 1979 in the first three months of 2009 and more dramatically than expected, suggesting recession may be deeper than feared. [
]UK March retail sales, however, rose 0.3 percent on the month, far better than analysts' forecasts of minus 0.5 percent.
"The market at the moment is focusing on leading indicators. With the Ifo out this morning from Germany, coming through better-than-expected, this is really the main focus for the market rather than the GDP numbers," said Gareth Evans, UK equity strategist at UBS.
German corporate sentiment rose in April to its highest level in five months, a closely watched survey showed, suggesting the downturn in Europe's largest economy may be easing. [
]"We have passed the worst in terms of downgrades of earnings. We are seeing leading indicators bottoming. Valuations are pretty pervasive. For those three reason, even if the market does come back from here, I'd still be looking to be constructive on the equity market," Evans said.
SLICK OILS, SHINY METALS
Oil producers added the most points to the index as crude <CLc1> traded near $50 a barrel. BP <BP.L>, Royal Dutch Shell <RDSa.L>, BG Group <BG.L>, Cairn Energy <CNE.L> and Tullow Oil <TLW.L> put on 1.6 to 3.2 percent.
Miners were firmer, with Kazakhmys <KAZ.L>, Vedanta Resources <VED.L>, Anglo American <AAL.L>, Xstrata <XTA.L>, Antofagasta <ANTO.L>, Eurasian Natural Resources <ENRC.L> and Rio Tinto <RIO.L> rising between 1.7 and 5.9 percent.
Amlin <AML.L> advanced 3.5 percent after Goldman Sachs upgraded the Lloyd's of London insurer to "neutral" from "sell" and removed it from its "conviction sell list".
BAE Systems <BAES.L> strengthened 4 percent after UBS added the defence contractor to its "most preferred alpha preference list", saying it offered high visibility of earnings growth, strong cash generation and a very attractive valuation.
Drugmaker AstraZeneca <AZN.L> rose 3.7 percent after European regulators recommended its drug Iressa for certain lung cancer patients late on Thursday.
Schroders <SDR.L> lost 2.8 percent, extending the previous session's 6.9 percent fall after its first-quarter results. Morgan Stanley on Friday cut its price target on the asset manager. (Editing by Rupert Winchester)
