British PM joins in 7-way TV debate ahead of general elections

British Prime Minister David Cameron on Thursday took part in a major televised debate with leaders of six other political parties ahead of the general elections in May.
It would be the only time for Cameron, leader of the Conservatives, and Ed Miliband, leader of the Labor party to join in the same TV debate before the polling day on May 7.
The debate, hosted by British TV network ITV, also invited the leaders of the Liberal Democrats, the UK Independence Party (UKIP), the Green Party, Wales' Plaid Cymru party and the Scottish National Party (SNP).
Cameron has refused to participate in a head-to-head TV debate with Miliband before the general elections.
