Bharatiya Janata Party (BJP) on Tuesday demanded immediate dismissal of the Trinamool Congress government in West Bengal in the wake of a sting operation and said that free and fair elections were not possible under the present dispensation.

The saffron party held a protest march in the city demanding dismissal of the TMC government, and later met Governor K N Tripathi on the issue.

"We met the Governor and placed our demands that the TMC government, whose ministers, MPs and other leaders were seen taking bribes, has no right to govern the state. We demand immediate dismissal of the government. Free and fair elections is not possible with the TMC at the helm of affairs in the state," BJP General Secretary Kailash Vijayvargiya told reporters.

"It is a shame. They have broken the trust of the people.

When public representatives of a party are taking bribes in return of favours, it is very shameful and condemnable," he said.

During the protest march, senior BJP leaders including Rahul Sinha were detained by police.

BJP had on Monday demanded resignation of West Bengal Chief Minister Mamata Banerjee and the CPI(M) sought President’s rule in the state.

Dubbing the sting operation by a news portal as "manufactured", TMC accused the Opposition of hatching a "political conspiracy" ahead of the Assembly elections.
