Mr Tindall and five others are accused of illegally possessing weapons. Charges against them were originally quashed but the Indian authorities appealed the decision and won the case following a trial. All of the men have always protested their innocence and they have been stranded in India ever since.
Speaking from Westminster, Mr Matheson said: “The government has encouraged a ‘softly, softly’ approach but enough is enough. We’ve tried the legal route – it didn’t work. Now let’s try the political route!”
Mr Matheson will ask a question in the House of Commons on foreign affairs this week where he plans to put renewed political pressure on senior Government Ministers to do something about this case.
