No clear poll leader after UK election TV showdown

The British general election remained on a knife-edge after no party leader managed to land a killer blow at the final set-piece TV event of the campaign.

With prime minister David Cameron refusing a head-to-head debate with the the only potential rival for his job, Labour’s David Miliband, the pair, plus Lib Dem leader Nick Clegg, each separately faced 30 minutes of intensive questioning by voters in a BBC special.

It was seen as perhaps the last major opportunity for either of the main party leaders to make a decisive breakthrough.
