LONDON, April 7 (Reuters) - Weak miners pushed Britain's top shares lower on Thursday, offsetting gains from banks on relief Portugal will seek financial help from the European Union.
By 1117 GMT, the FTSE 100 <
> was off 13.42 points, or 0.2 percent, at 6,027.71, unaffected by the Bank of England's decision to keep interest rates at a record-low 0.5 percent, despite a surge in inflation. [ ]"There was no surprise that the Bank of England left their rates unchanged, hence we're seeing no reaction on the FTSE," said Yusuf Heusen, senior sales trader at IG Index.
"We've got the European rate decision (at 1145 GMT). It's going to go up a quarter of a percent I reckon, which is what is forecast, and is all factored in."
Miners <.FTNMX1770> exerted the most downward pressure on the index, falling back after a good run over the past two weeks, with traders saying thin volumes were exaggerating share price movements.
Vedanta Resources <VED.L> and Cairn Energy <CNE.L> were among the sharpest FTSE 100 fallers, off 3 percent and 2.1 percent, respectively, after the companies extended the deadline for a $9.6 billion acquisition of Cairn's Indian assets, a day after the Indian government deferred a decision on the deal. [
]"Although clearly a disappointment, and likely to result in some further weakness, the deal is not yet dead," broker Collins Stewart said in a note on Cairn Energy.
Banks <.FTNMX8350> rose as Portugal followed Greece and Ireland in asking for financial aid after months of what many economists said was a refusal to acknowledge economic reality. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Peter Dixon, an economist at Commerzbank, shrugged off the concerns felt by some investors that Spain could be the next to feel the heat.
"I don't share the views of the pessimists who think that just because one domino has fallen then another one is inevitably going to fall as well," he said.
"It may be weighing on the markets at the margin, but I think ... the situations differ hugely, and we're not looking at any imminent problems in Spain."
