Leading a march of the Punjab Congress to Lakhimpur Kheri in Uttar Pradesh (UP), the state party chief Navjot Singh Sidhu on Thursday threatened to go on a hunger strike if Union Minister Ajay Kumar Mishra’s son Ashish Mishra is not arrested by Friday in connection with the death of eight farmers during violence in UP.

Union Minister of State for Home Ajay Mishra’s son has been booked for allegedly mowing down four farmers in Lakhimpur Kheri on Sunday. Mishra has, however, denied allegations about his son’s involvement in the case.

Keeping his threat to stage a march towards Lakhimpur Kheri in Uttar Pradesh if Misra’s son Ashish Misra is not arrested, Sidhu today led a protest march from Punjab to Lakhimpur Kheri in protest against the killing of farmers.

A large number of party leaders including ministers, legislators and workers first assembled at Mohali (adjoining Chandigarh) and then headed towards Lakhimpur Kheri in their vehicles. Chief Minister Charanjit Singh Channi also joined Sidhu for a brief period when the march was about to start.

Sidhu had resigned from the post of Punjab Congress chief on September 28 but it wasn’t immediately clear if the resignation was withdrawn. Before the protest march Thursday, Sidhu slammed the BJP-led government in UP over the Lakhimpur Kheri incident.

He said Punjab Congress MLAs are standing firmly with the farmers. He asked why UP authorities haven’t taken action against Mishra’s son even after an FIR was lodged in the matter. “Are union minister and his son above the law and Constitution?” he asked.

“This fight is for our farmers,” he said, adding: “If UP police do not arrest the union minister’s son, I will go on hunger strike. It is my “vachan” (promise).”

Later, he said, “If the arrest is not made till tomorrow (Friday), or he does not join investigation, I will go on a hunger strike,” adding that Congress leaders Priyanka Gandhi Vadra and Rahul Gandhi are “saviours of democracy.”

Earlier, Punjab Congress working president Sukhwinder Singh Danny said they would stage a sit-in wherever they were stopped from heading towards Lakhimpur Kheri. Congress legislator Sunder Sham Arora said they were ready for courting arrest if prevented from going to UP.

Four of the eight people who died in Sunday’s violence in Lakhimpur Kheri were farmers, allegedly knocked down by vehicles driven by BJP workers travelling to welcome UP Deputy Chief Minister Keshav Prasad Maurya to an event in the area.

Two BJP workers, Mishra’s driver, and Raman Kashyap, a journalist working for a private TV channel, were also killed in the incident.

While the first three were allegedly lynched by agitating farmers, the scribe, according to his father, died after being hit by a vehicle when he was covering farmers’ protest against Maurya’s visit to Mishra’s native place. No arrests have been made in connection with the case so far.
