BJP state president Kummanam Rajasekharan said when police informed the Chief Minister that there was a possibility of protest against the alleged "violence of politics" by CPI(M) by certain organisations, Vijayan himself took the decision not to attend the function.
Rajasekharan said even though police later told him that the protesters have been pacified, Vijayan said he was returning after cancelling the programme.
Madhya Pradesh Chief Minister Shivraj Singh Chouhan and DGP had contacted Vijayan over phone when they came to know about the incident, he pointed out.
Rajasekharan said CPI(M)'s style of attacking political rivals did not exist in any other states.
Earlier in the day, Vijayan had lashed out at Madhya Pradesh Police over inaction against RSS, saying the experience he underwent in the BJP-ruled state is a reflection of the culture of the Sangh Parivar and the government supported by them.
