12:33 The Secretary of State for Foreign and Commonwealth Affairs (Mr William Hague)
Our embassies and high commissions are the essential infrastructure of our country’s influence overseas and of our economic recovery. They provide an early warning system for threats to our security and to wider peace, and assist British nationals in times of crisis. They support our economy and help British businesses to access markets abroad. They promote our values of democracy and political freedom across the world, and help to craft vital international agreements from nuclear proliferation to climate change. We could not do without them for a single day.
