The UK is committed to working towards a world free from nuclear weapons and to zero tolerance of proliferation. We will use the Nuclear Non-Proliferation Treaty 2008 Preparatory Committee to take forward work to strengthen the treaty. The UK will promote consensus around key measures encompassing the treaty's three pillars: zero tolerance of proliferation; safe, secure and peaceful use of nuclear technology; and a reinvigorated commitment to a world free from nuclear weapons.
The UK has now met the commitment outlined in the 2006 White Paper on the future of the UK nuclear deterrent to reduce the number of operationally available warheads to fewer than 160. The explosive power of our nuclear arsenal has been reduced by 75 per cent since the end of the Cold War.
