A British human rights barrister has been expelled from Russia for visiting the country on the wrong type of visa. Bill Bowring, a professor at Birkbeck College, University of London, who has represented Chechens who have accused the Russian military of abuse, was told to leave after immigration officials ruled he should have been travelling on a business visa and not a tourist one. The professor had already given several training lectures to local judges when officials questioned him at his hotel in Astrakhan, southern Russia. He was fined and ordered to return to London.
