Anti-nuclear campaigners today welcomed Treasury minister Danny Alexander's commitment to ensure a full and open debate on the future of Britain's nuclear weapons.
A government review will provide "credible" alternatives to the like-for-like replacement of Trident, Mr Alexander said.
The Lib Dem dismissed Tory demands for a new continuous at-sea nuclear deterrent as "not financially realistic."
Mr Alexander took charge of the study last autumn after Lib Dem defence minister Nick Harvey lost his job in a reshuffle.
CND general secretary Kate Hudson said: "Danny Alexander is right to point out what he describes as the 'real significance of this debate for the future of our country.'
"It's high time that Labour and the Tories realise that a blind commitment to wasting well over £100bn on a new nuclear weapons system is not what the public want.
"If that still doesn't convince them then how about the fact that it's unusable, strategically redundant and not even the military want it."
Fire Minister Brandon Lewis probably had a fair idea what Sir Ken Knight would deliver when he asked him to conduct an "independent" report into fire and rescue services in England.
