* Banks weak ahead of Goldman Sachs results
By David Brett
LONDON, Jan 21 (Reuters) - Britain's top share index was up 0.2 percent by midday on Thursday as strength in drugmakers offset weak miners, on an uncertain demand outlook in China, with banks down ahead of Goldman Sachs' fourth-quarter results.
By 1156 GMT, the FTSE 100 <
> index was 0.20 points lower at 5,431.00, having posted its biggest one-day fall in a month on Wednesday on the back of speculation of fiscal tightening in China and downbeat U.S. banking results.Miners fell back as metal prices retreated amid fears that China could tighten fiscal policy after data released overnight showed China's economy expanded by 10.7 percent between October and December, compared with a year earlier, up sharply from 9.1 percent in the third quarter.

]Rio Tinto <RIO.L>, Xstrata <XTA.L>, BHP Billiton <BLT.L>, Anglo American <AAL.L> and Kazakhmys <KAZ.L> were among the biggest fallers, down 1.2 to 3.6 percent.
"The market has taken countenance of news that came out last night and translated that to what is happening over here... be it that could be a correction, which most commentators agree has been coming for a while and which is not necesarily a bad thing," said Howard Wheeldon, strategist at BGC Partners.
Wheeldon added that investors used an early morning spike in prices to wind down or get out of positions in anticipation of what might happen once New York opens this afternoon.
Banks remained depressed ahead of more fourth-quarter earnings figures from the U.S., this time from Goldman Sachs <GS.N>.
Barclays <BARC.L>, Royal Bank of Scotland <RBS.L>, Lloyds Banking Group and Standard Chartered <STAN.L> were down 1.9 to 3.7 percent.
Worries have built up over the state of the industry following a glut of disappointing updates from U.S. banks in the past week.
Among individual fallers, supermarkets group Wm Morrison <MRW.L> shed 1.4 percent as cautious comments about 2010 and the lack of news on a new chief executive outweighed the biggest rise in Christmas sales among Britain's top four grocers. [
