Swami Ramdevji arrives for Glasgow yoga class after immigration row Hundreds of people have turned out for a yoga masterclass in Glasgow led by Indian guru Swami Ramdevji. The 47-year-old's visit to Scotland had been put in jeopardy after airport officials detained him at Heathrow for several hours on Saturday. He was eventually cleared to travel onwards after an intervention by Labour MP Keith Vaz, who called the episode "extremely serious." The event at the Emirates Arena attracted around 2000 of the guru's devotees. The Home Office declined to comment on reports that the weekend row centred on whether he was travelling on a tourist or a business visa. His supporters claimed he was being targeted because he had spoken out against corruption in his home country. Mr Ramdevji, also known as Baba Ramdev, bought the island of Little Cumbrae, off the Ayrshire coast, two years ago with plans to turn it into a yoga centre. He owns a television channel in India and is reputed to have an 85 million-strong global following. Mr Vaz has said he will be seeking a full explanation from Heathrow's head of immigration into the reason for Mr Ramdevji's detention. He said: "No Indian citizen with a valid visa entering the UK for lawful purposes should be held in this way.
