Trident is a UK nuclear missiles programme based on four submarines armed with nuclear weapons and able to deliver thermonuclear warheads from multiple vehicles. It was announced in 1980 and is still active. Its original purpose was to discourage aggression against the UK during the Cold War. A great number of demonstrations against Trident have been taking place over the time, including activist actions performed by the Campaign for Nuclear Disarmament and Trident Ploughshares. Thousands of supporters of the Campaign for Nuclear Disarmament joined the protest in London where they wrapped a huge pink-coloured scarf around the Ministry of Defence. “They should know that scrapping Trident is a vote winner, not a vote loser," said Kate Hudson, CND general secretary. "The British people will not stand for masses of our taxpayers' money being spent on nuclear weapons."
