AFTER the chill the nuclear tests brought in last summer, some of the old warmth is creeping back into Indo-British relations. British foreign secretary Robin Cook, who mouthed some of the most hostile language over the nuclear tests, is now speaking of making a new beginning. After a near-freeze in exchanges, ministers of both countries are rushing to rebuild bridges. British deputy prime minister John Prescott will visit India soon, preceded by economic secretary at the Treasury, Patricia Hewitt. From the Indian side, external affairs minister Jaswant Singh will be in London this week (February 2-5) to shore up the gains made during special emissary Brajesh Mishra's visit to London a week ago.
