Sri Lanka's health minister is the third minister in weeks to face calls for his resignation, after a no-confidence motion was handed over to the Speaker.
The motion against Rajitha Senaratne was signed by 39 Joint opposition MPs, the Daily Mirror reported.
This week, the justice minister was expelled from parliament after UNP MPs accused him of stalling investigations into corruption and fraud by the previous government.
The finance minister was earlier forced to resign over allegations of corruption.
