When Gordon Brown arrived in India for his first trip there, he probably had a clear idea of what would be involved. He would visit Bangalore to get a first-hand look at the Indian hi-tech miracle; he would discuss world trade; he would make a speech or two, burnishing his credentials as a prime minister-in-waiting. Hell, if he was lucky, he might even get time to take in a bit of culture - the Taj Mahal, that sort of thing.

What the chancellor cannot have imagined is that he would be dragged into a diplomatic incident, sparked by events in a reality TV show back in Britain.
