Glencore International was in the top spot after finally completing the merger with fellow miner Xstrata. Oil and gas conglomerate BG Group was also a strong riser after it cheered investors with a one per cent rise in revenue and other operating income. Financial services group Legal & General was higher after hailing record assets, sales and cash generation in the first quarter of 2013 as its UK and US businesses exceeded management's expectations. Medical technology group Smith & Nephew rose after it said it plans to give back $300m to shareholders in a buyback plan. The group, which makes artificial hips, said the buyback is part of its new capital allocation framework for further investments and acquisitions. Meanwhile, drug maker Shire lifted first-quarter earnings 10% but revenues missed consensus estimates by 5.0 per cent. Product sales in the three months to end-March 2013 were up 1.0% to $1.1bn against a strong set of comparatives from the equivalent period in 2012, but this was less than analysts were expecting.
