New Delhi1, Sep 17 - The Bharatiya Janata Party (BJP) Thursday slammed Minister of State for External Affairs Shashi Tharoor terming his twitter remarks about 'cattle class' travel as an insult to a large middle class who led an austere lifestyle.

Tharoor ran into trouble for a message he posted as a reply to someone on the social networking site Twitter, in which he said he would travel 'cattle class out of solidarity with all our holy cows!' The question was about Congress leaders travelling economy class as part of austerity measures.

BJP spokesperson Rajiv Pratap Rudy said: 'Tharoor has termed economy class in airlines as cattle class. (This reflects) the insensitivity of the minister. This tantamounts to (causing) deep injury to the self-respect and esteem of millions who travel economy class,' Rudy said in a statement here.

He said Tharoor's remarks show his arrogance typical of Congress leaders.
