Maharashtra BJP in-charge C T Ravi on Tuesday dubbed Uddhav Thackeray a part-time chief minister and dared the Shiv Sena-led Maha Vikas Aghadi (MVA) government to dissolve the Legislative Assembly and hold fresh polls, which he said would prove BJP's strength.

Speaking at the BJP state executive meeting here, Ravi said Shiv Sena had betrayed BJP and the people of Maharashtra by joining hands with NCP and Congress to come to power.
