our paris correspondent, hugh schofield, explains how this could benefit britain. >> france, which generates electricity via nuclear power, has done for 50 years, made a strategic decision back in the 1960's, and the goal is the preeminent player in the field of nuclear power. britain wants some of that, and it's developing its own nuclear stock because it has to abate its energy supply network, so it's building, and it wants french know-how. it also wants to start building up its own know-how, building up its own capacity to generate nuclear technology to export nuclear technology. so this is not just about buying into the french, it's also about building up british expertise. >> libyans are marking precisely one year since the start of the revolution which toppled colonel muammar gaddafi. he was ousted from power after more than 40 years, of course. celebrations planned in towns and cities right across the country. that is amidst fears of instability there, largely because some of those brigades of former rebel fighters have still not handed over their weapons. gabriel gatehouse is in trip
