The government and farm unions reached some common ground on Wednesday to resolve protesting farmers'' concerns over rise in power tariff and penalties for stubble burning, but the two sides remained deadlocked over the main contentious issues of the repeal of three farm laws and a legal guarantee for MSP.

After nearly five hours of the sixth round of negotiations between three union ministers and a 41-member representative group of thousands farmers protesting on Delhi borders, Agriculture Minister Narendra Singh Tomar said at least 50 per cent resolution has been reached with mutual agreement on two out of four items on the agenda and discussions would continue on the remaining two on January 4.
