* FTSE 100 off 1 percent
* Miners weak, hit by easing metals prices
* BoE says UK economic outlook uncertain
By Tricia Wright
LONDON, Nov 10 (Reuters) - Britain's top share index fell to a one-week closing low on Wednesday, pressured by miners on fears over softening demand from China after downbeat import data, with worries about Ireland's debt also darkening the mood.
The FTSE 100 closed down 58.25 points, or 1 percent, at 5,816.94. The index ended up 0.4 percent on Tuesday at 5,875.19, having briefly broken through the 5,900 level for the first time since June 2008 earlier in the session.
Miners retreated after a recent advance sparked by the Federal Reserve's decision to pump more cheap money into the economy, led down by platinum miner Lonmin, off 4.7 percent, as metals prices fell.
Sentiment surrounding the sector was soured after data showed October import growth in China, the world's biggest consumer of metals, was slower than expected. Investors were looking ahead to Chinese CPI data, due to be released overnight.
Oil stocks and banks also fell back after recent gains.
"(Investors are) uneasy given ongoing concerns over... Ireland, and there is also some weakness in metals pulling the FTSE back," Mic Mills, head of electronic trading at ETX Capital, said.
"The downward momentum from yesterday appears to be still in evidence this afternoon as investors look to take some profit from the recent rally," he said.
Borrowing costs in Ireland have reached record highs this week as Dublin plans to push through hefty spending cuts and tax hikes in an effort to convince investors it is not on the verge of financial meltdown.
Meanwhile the Bank of England said there was uncertainty among its Monetary Policy Committee on the economic outlook for the UK.
British inflation will fall below target in two years' time, the BoE forecast, but said the outlook was highly uncertain and it stood ready to change policy in either direction.
ROLLS-ROYCE WEAK
