The London market was lower in afternoon trading after mining stocks tumbled following a rise in the value of the dollar knocking commodity prices.
The FTSE 100 Index fell 34.8 points to 6824.1, after the dollar rose against a basket of major currencies following weekend comments from US Federal Reserve Vice Chairman Stanley Fischer that the US was close to its inflation and jobs targets prompting speculation that the central bank could raise interests later this year. The FTSE 250 Index fell 40.3 points to 17833.8.
The greenback lifted 0.3% against a number of major currencies, although the pound rose 0.2% against the dollar to 1.31.
CMC Markets chief market analyst Michael Hewson said: "Mining stocks have slid back as gold and silver prices have come under pressure on a stronger US dollar, with Fresnillo and Randgold Resources among the biggest losers."
