LONDON, Nov 9 (Reuters) - Britain's leading share index rose 1 percent on Monday, up for the fourth consecutive session, led by heavyweight banks, miners and oils with risk aversion supported as the Group of 20 pledged to keep the aid flowing.

By 0901 GMT, the FTSE 100 was up 47.25 points or 0.9 percent higher at 5189.97, after the index closed up 0.3 percent at 5142.72 on Friday for a weekly gain of 2 percent, its best weekly performance for a month.

With little in the way of domestic economic or corporate news to guide investors Monday, UK shares took their cue from Asia, where shares outside Japan .MIAPJ0000PUS added 1 percent.

"The corporate story will unfold as the week goes on with investors looking to the upside following good figures from the U.S. last week and the expectation of better performances from Barclays and HSBC on Tuesday," said Richard Hunter, Head of UK equities at Hargreaves Lansdown.

Miners led the way as metal prices continued to soar on the increasing optimism on the outlook for demand, with gold remaining above the $1,100 level after hitting an all-time high on Friday.

BHP Billiton (BLT.L) and Rio Tinto (RIO.L), who have previously been involved in takeover discussions, rose 2.5 and 2.4 percent respectively.

Anglo American PLC (AAL.L) gained 2.1 percent while ENRC (ENRC.L), Kazakhmys (KAZ.L), Lonmin (LMI.L) and Fresnillo FRSE.L climbed 1.7 to 2.9 percent.

Energy issues were also in positive territory as crude hovered around the $80 a barrel level, while the price of long-term oil futures crept towards the $100 mark.

Heavyweights BP (BP.L), BG (BG.L) and Royal Dutch Shell RDSA.L rose 1 to 1.4 percent.
