FOREIGN Secretary Jack Straw has advised Britons to consider leaving India because of the threat of war with its nuclear rival Pakistan.

The families of UK Government staff and less-essential staff will be offered the chance to return home, Jack Straw said.

Mr Straw issued the new advice following a similar move by the United States.

The Foreign Office estimates there are about 20,000 British nationals living in India, not all of them registered with consular officials. Some 700 Britons are registered in Pakistan.

The warning comes after Mr Straw visited the region in a bid to stop the neighbouring countries' slide towards war over the disputed region of Kashmir.

The Foreign Secretary said: "One Wednesday in New Delhi, I said that whilst the situation between India and Pakistan was dangerous, war was not inevitable.

"That remains my view and we are working as hard as we can to secure a peaceful resolution of the long-standing conflict.

"However, I do have a clear duty of care in respect of both UK citizens and of UK staff in diplomatic posts abroad."

That meant travellers were advised against visiting the country and those already there should consider leaving, he said.

The families of British Government staff and those staff not engaged in essential work are being offered the opportunity to come home.

The visa service will continue but at a reduced level, Mr Straw said.

"The United States is taking similar action. Obviously when and if the situation improves the travel advice and the arrangements for our staff will be changed accordingly," he added.
