LONDON, Nov 18 (Reuters) - Britain's top share index was up 0.4 percent at midday on Wednesday, helped by strength in mining and energy shares which were underpinned by firmer commodity prices, offsetting a defensive drag as risk appetite hardened.
At 1155 GMT, the FTSE 100 <
> was up 20.98 points at 5366.91, after closing 0.7 percent lower on Tuesday."The UK market is being underpinned by mining stocks ... Dollar weakness is also keeping commodities at decent levels," said Anthony Grech, market strategist at IG Index.
"A sharp (dollar) rally may have the further knock-on effect of pushing down the heavily-weighted mining and energy sectors on the FTSE. However, the recent year-highs for equity markets will have bolstered confidence," he said.
