British Prime Minister David Cameron on Wednesday said Pakistan could not be allowed to harbour militants and promote terror against India, Afghanistan and the rest of the world.
Cameron, on his first visit to India after becoming prime minister in May, laid out the basis for a new "enhanced relationship" with India.
Cameron's business minister Vince Cable said the UK was prepared to export civil nuclear technology to India, bringing Britain in line with the stances taken by the US, Russia and France.
Travelling to Bangalore and later to New Delhi, Cameron signed a £700 million deal for the Indian Air Force and Navy to buy 57 more Hawk Advanced Jet Trainer aircraft from British Aerospace Systems. India had signed an earlier agreement to buy 66 Hawk trainers.
Cameron said US President Barack Obama was in agreement with him on Pakistan.
"We want Pakistan to emerge as a strong, stable and democratic nation. We cannot tolerate in any sense the idea that this country is... able, in any way, to promote the export of terror, whether to India," Cameron said during his visit to the Infosys headquarters in Bangalore.
