LONDON, May 7 (Reuters) - Britain's FTSE 100 <
> index rose by midday on Wednesday as near record high crude prices lifted oil shares and banks reversed earlier losses, offsetting weakness in miners.By 1032 GMT, the UK's blue-chip index was up 40 points, or 0.6 percent at 6,255.2 after ending the previous session flat. The FTSE 100 has risen 15 percent since March 17 when the index hit its year's lowest closing level, but it is still down 3 percent for the year.
