THOUSANDS of protesters will spectacularly encircle the Ministry of Defence today against a £100 billion renewal of Britain’s nuclear submarines — as scientists warn that the threat of a holocaust is at its highest for decades.

The mass Campaign for Nuclear Disarmament (CND) demo will be surrounding the building with a seven mile-long scarf, which has been knitted by thousands of volunteers from around the world as part of their Wrap Up Trident campaign ahead of this year’s general election.

The new government will make a final decision on Trident replacement next year, and CND general secretary Kate Hudson predicted yesterday that it would become a “huge election issue.”
