LONDON, Feb 20 (Reuters) - European shares fell on Wednesday after Alliance & Leicester <ALLL.L> and BNP Paribas <BNPP.PA> unveiled debt writedowns and U.S. consumer inflation data rose more than expected last month.
Banks were among the worst performers on the broader European market as renewed concern about corporate profitability in light of difficult conditions in the credit market and a slowing economic backdrop weighed on the entire sector.
The FTSEurofirst 300 index <
> of top European shares closed down 1.2 percent at 1,321.01 points, having fallen earlier by as much as 1.8 percent.Britain's Alliance & Leicester shed nearly 7 percent after it warned of sharply higher funding costs and took a 185-million pound ($360.4 million) writedown on risky assets.
BNP Paribas, France's biggest listed bank, took an 898-million-euro writedown during the fourth quarter, leaving its shares down 0.5 percent.
"Weak economic data, disappointing corporate earnings and the possibility of future writedowns creates a perfect storm of uncertainty," said Barclays Wealth strategist Henk Potts.
"People are looking for signs in terms of what is happening in the U.S. economy and the possible risks associated with that and the data continues to be a bit disappointing."
The FTSEurofirst 300 has fallen by 20 percent since reaching a 6-1/2 year high in July last year, dragged down largely by uncertainty over the outlook for the heavyweight financial sector as the credit crisis erupted.
Among the banks on Wednesday, HSBC <HSBA.L> was down 1.4 percent, Royal Bank of Scotland <RBS.L> fell 1 percent and Societe Generale <SOGN.PA> dropped 6 percent.
European credit derivative indexes hit new all-time peaks as fears of the bank writedowns, unwinding of structured credit products and the gloomy economic outlook hit sentiment, which analysts believe will also undermine equities.
Further undermining financials were comments from Juergen Ruettgers, the premier of the German state of North-Rhine Westphalia, who said the country's regional state-backed landesbanks were in crisis.
The region is home to stricken state-owned bank WestLB.
VODAFONE HURTS TELECOMS
Telecoms took a knock after Vodafone's <VOD.L> U.S. joint venture said it had started offering flat rate plans for unlimited calls which raised concerns a price war could erupt.
Vodafone shares fell 4.7 percent. Fixed-line telecom groups Deutsche Telekom <DTEGn.DE> and Telecom Italia <TLIT.MI> shed between 0.5 and 3.1 percent, while BT <BT.L> lost 1.6 percent.
A 1-percent drop in the price of crude oil futures did little to dispel concerns about inflation, especially after U.S. consumer inflation data showed a second monthly increase because of soaring food costs.
Total <TOTF.PA>, BP <BP.L> and Royal Dutch Shell <RDSa.L> all fell between 1.6 and 2.5 percent.
"Oil near $100 is worrying people about inflation, especially about its impact on consumers that can dampen spending," said BNP Paribas strategist Edmund Shing.
"Two defensive sectors that you would expect to do well are falling: telecoms on the price war worries and foods and beverages on commodity price inflation," he added.
Another defensive stock, Dutch brewer Heineken NV <HEIN.AS>, shed 6 percent after reporting 2007 net profit in line with its guidance but flagging rising costs in 2008.
Among the few gainers on the broader European market was Dutch financial services group ING <ING.AS>, which rose 0.9 percent after taking a lower-than-expected impairment charge of 194 million euros on its riskier investments in its fourth-quarter results.
Around Europe, Britain's FTSE 100 <
