The resignation of an advisor who accused the Ministry of Defence of “ignoring its own advisory group” has called into question the future of a project aimed at dismantling nuclear submarines in central Plymouth.

The Prime Minister, Gordon Brown, is reported to be considering a proposal to scrap a quarter of the nuclear warheads owned by the British government. The news follows pressure for cuts in the light of similar moves by the USA and Russia.

The US President Barack Obama has won this year’s Nobel Peace Prize for “extraordinary efforts to strengthen international diplomacy and co-operation”. Campaigners welcomed the news but urged Obama to live up to the Prize.

The Prime Minister, Gordon Brown, has been criticised for avoiding the issue of Trident in his speech to the Labour Party conference yesterday, despite the increasingly vocal opposition to its renewal.

The United Nations Security Council has voted unanimously in favour of the need to work towards a world free of nuclear weapons. The vote is seen as a step towards international agreements on reducing nuclear arsenals.

The Prime Minister Gordon Brown is to respond to growing public pressure by announcing a cut in the number of Trident nuclear submarines from four to three. Campaigners welcomed the news but insisted that the cuts must go further.

New research published by Greenpeace and backed by senior politicians has warned that the cost of replacing the UK’s Trident nuclear weapons system will be over £95 billion – in contrast to the roughly £20 billion earmarked by the government.

The US President, Barack Obama, has abandoned controversial plans to site a missile system in Poland and the Czech Republic. The decision is likely to ease tensions in the USA’s relations with Russia.

The government's plans to renew the Trident nuclear weapons system have taken another blow with a poll revealing that voters would rather scrap nuclear weapons than see public spending cuts affecting health or education.

The Prime Minister has been challenged over his allegedly inconsistent approach to nuclear weapons, following an arms reduction agreement between Russia and the USA.
