THE lady in the sari was late to the dinner. "I'm looking for my husband," she said at the door. "He must be at one of the tables," a hostess replied innocently; it took someone else to identify Cherie Blair. Then on she was applauded all the way to the top table in her now famous red-and-green silk sari. That sari said elegantly, perhaps even eloquently, far more than all those friendly words traded between Tony Blair and Inder Kumar Gujral in Edinburgh a few weeks before. India and Britain weren't just friends, this evening they were falling all over one another.
