London's blue chip index held on to gains in morning trade, recovering after a six-day sell-off. While markets are still concerned with the ongoing troubles in the Eurozone, fears over the credit rating of the US eased after Standard & Poor's and Moody's reiterated their ratings last night.Nevertheless, as expected the US bipartisan 'supercommittee' admitted yesterday that they have not agreed on a plan to cut the nation's deficit by $1.2trn. "Despite our inability to bridge the committee's significant differences, we end this process united in our belief that the nation's fiscal crisis must be addressed and that we cannot leave it for the next generation to solve," according to a joint statement by Republican representative Jeb Hensarling and Democratic senator Patty Murray. The news has weighed on defence stocks in London, with BAE Systems, Meggitt and Chemring suffering. If the committee fail to come up with a plan to cut the deficit, the Pentagon - as agreed in August - will start making cuts totalling between $500-600bn from January 2013.In domestic news, public sector borrowing fell in October compared to the year before, according to the latest figures from the Office for National Statistics (ONS).
