AlHijjah 17, 1434, Oct 22, 2013, SPA -- Britain's top share index edged up to 11-week highs on Tuesday, helped by strong updates from consumer goods maker Reckitt Benckiser, hospitality specialist Whitbread and miner BHP Billiton, Reuters reported. Reckitt offered the biggest boost to the FTSE 100, its shares up 5.3 percent after solid third quarter sales prompted a rise in full year guidance, as a recovery in developed markets offset some weakness in emerging economies. The corporate earnings boost helped the FTSE 100 outperform slightly weaker pan-European markets, with the British benchmark up 9.85 points or 0.2 percent at 6,664.05 by 0958 GMT, hitting its highest levels since early August. Also among the top risers, BHP climbed 3.3 percent after upgrading its iron ore production target in what analysts at Morgan Stanley called a "very solid" update.
