Michael Portillo on Trident nuclear replacement plans
Renewing Trident would not be a good idea as the system is "completely past its sell-by date", said former Conservative defence secretary Michael Portillo.
Mr Portillo, who served in the post under John Major from 1995-97, claimed the nuclear system was a "waste of money" and no deterrent for the Taliban, when he spoke to Andrew Neil on This Week.
Conservatives are backing a like-for-like replacement but the Liberal Democrats are opposing it. Defence Secretary Philip Hammond has announced £350m is to be spent on design work, but a final decision is not due until 2016.
