A group of Haryana farmers protesting against the Centre’s three agri-marketing laws, showed black flags to the convoy of state Chief Minister Manohar Lal Khattar when he was passing through Ambala city, sources said.

According to them, some of the farmers tried to block Khattar’s motorcade but the police managed to provide a safe passage to the chief minister.

Khattar had come to Ambala to address public meetings in support of party's mayoral and ward candidates for the upcoming civic bodies polls.

The farmers waved black flags at the chief minister's convoy while it was crossing the Agrasen Chowk. They also raised slogans against the government and said that they would continue to protest till the three farm laws are not repealed.

A large number of police personnel were deployed near the Chowk.

The farmers had gathered at the grain market and also tried to block the Ambala-Hisar highway.

On December 1, a group of farmers had shown black flags to Union minister Rattan Lal Kataria in Jandli village adjoining Ambala city.

Kataria is a BJP MP from Ambala.

Almost two weeks later, BJP MP Nayab Singh Saini faced the ire of farmers in Yamunanagar as they raised slogans against the Centre for not repealing the three agri laws.

Saini, an MP from Kurukshetra, was visiting Khurdi village to lay the foundation stones of some projects and inaugurate a community centre. The protesters had thrown black paint on the foundation stones.
