London - Britain's top share index climbed to a two-week high on Wednesday, with a rise in mining and energy stocks on the back of firmer commodity prices and a rally in retailers supporting the market.
The blue-chip FTSE 100 index was up 0.4 percent at 6,858.97 points by 08h07 GMT after rising to 6,861.66 points, the highest level since June 11.
Miners were in demand, with the UK sector index rising 1.1 percent, tracking a 0.2 to 0.5 percent gain in major industrial metals such as copper and aluminium.
“A rise in metals prices and recent data showing an improvement in Chinese manufacturing are providing a tailwind to the market, but investors will continue to be cautious as we haven't yet seen a firm direction for commodity prices,” said Keith Bowman, equity analyst at Hargreaves Lansdown.
The UK oil and gas index gained 1.3 percent, the top sectoral gainer, after oil prices rose on hopes for stronger than expected US crude demand, while doubts over the prospect of reaching an agreement next week on Iran's nuclear programme eased oversupply concerns.
