* Miners, oils up as commodity prices rally
* Banks higher; RBS, Lloyds results due this week
* Pharmas weak; defensive attractions fade

LONDON, Feb 22 (Reuters) - Britain's leading shares were 0.1 percent higher at midday on Monday, extending recent gains in to a sixth straight session helped by strength in heavyweight miners, oils and banks, offsetting weakness in defensive issues.
By 1140 GMT, the FTSE 100 <
> index was 5.35 points higher at 5,363.52, having closed up 0.6 percent on Friday, its highest closing level in a month, and posting its best weekly performance since July."We have seen the defensives lag with both the tobacco and pharma sectors lower, which indicates that whilst investors are not doing too much today, they are not running scared either," said Joshua Raymond, market strategist at City Index.
"There has not been enough news out there to wet the appetites and get stocks moving so investors may simply be waiting in the wings," Raymond said.
Banks saw the most support as investors looked ahead to full-year results from part-nationalised Royal Bank of Scotland <RBS.L> and Lloyds Banking Group <LLOY.L> later this week, and worries over the sector's exposure to Greek debt problems faded.
RBS and Lloyds added 1.8 and 2.0 percent, respectively.
Barclays <BARC.L>, which posted better than expected earnings last week, gained 1.8 percent, while HSBC <HSBA.L> took on 0.1 percent and Standard Chartered <STAN.L> firmed 0.9 percent.
Britain's opposition Conservatives announced plans on Sunday to encourage taxpayers to buy shares in banks that were part-nationalised during the credit crunch, presenting this as a "people's bank bonus". [
]The plans, however, were dismissed by Business Secretary Peter Mandelson as a "silly little gimmick", the Financial Times reported.
Separately, Mandelson said on Sunday that Britain's loss-making, bailed-out banks should be restrained as they decide on bonuses for top executives ahead of reporting their annual results this week. [
]Miners were also in demand as the gold price moved higher, benefitting from a slip back in the dollar. Vedanta Resources <VED.L>, Kazakhmys <KAZ.L>, Eurasian Natural Resources <ENRC.L>, and Antofagasta <ANTO.L> gained 1.7 to 2.7 percent.
Rio Tinto <RIO.L> added 2.0 percent. The global miner said it had started iron ore production at a $901 million mine in the Robe Valley in Australia's Pilbara region. [
]Xstrata <XTA.L> gained 1.2 percent. Glencore, the Swiss commodities trader, is sounding out potential partners as it prepares to buy back the $2.5 billion Prodeco coalmine owned by Xstrata <XTA.L>, The Times said on Monday.
Energy issues were higher as crude prices <CLc1> hovered around $80 a barrel, having hit a six-week high earlier on Monday. BP <BP.L>, Royal Dutch Shell <RDSa.L>, BG Group <BG.L>, Tullow Oil <TLW.L and Cairn Energy added 0.3 to 0.7 percent.
Among individual blue chip gainers, packaging firm Bunzl <BNZL.L> topped the FTSE 100 leaders board, up 3.4 percent after it posted forecast-busting full-year results, which prompted Panmure Gordon to up its rating to "buy". [

DRUGS WEAK
GlaxoSmithKline <GSK.L> was the top FTSE 100 faller, down 2.1 percent. Two U.S. drug safety reviewers have recommended that Glaxo's diabetes drug Avandia be pulled from the market after concluding it is more dangerous to the heart than a rival medicine. [
]Peer Shire <SHP.L> shed 1.8 percent, giving back some of Friday's post-results advance as Panmure Gordon cut its rating to "sell" from "hold", while AstraZeneca <AZN.L> fell 0.2 percent as the defensive attractions of the sector waned.
Among other weak defensively-perceived issues, British American Tobacco <BATS.L> shed 1.1 percent, drinks group Diageo <DGE.L> lost 1.0 percent and food retailer Tesco <TSCO.L> fell 0.8 percent.
General retailers were also weak, with Marks & Spencer <MKS.L> off 1.8 percent as Bernstein Research cut its target price, while Next <NXT.L>, Kingfisher <KGF.L> and Home Retail Group <HOME.L> fell 0.3 to 1.4 percent. (Editing by Jon Loades-Carter)
