Thousands of farmers agitating against the three new central agriculture laws stayed put at their agitation venues near Delhi, which is going through a harsh spell of winter, unrelenting in their demand of withdrawal of the legislations.

On Wednesday, a cold wave swept Delhi as the minimum temperature dipped to 3.5 degrees Celsius. It is likely to get even colder on New Year's Eve, the India Meteorological Department predicted, as dry and icy winds barrelled through the plains.

The farmers protesting against the new agri laws had reached Singhu border over a month ago. The Centre and the protesting farmer unions will resume stalled talks on Wednesday with the latter sticking to their hardline position that the parleys will only be on the modalities of repealing the three new agri laws and giving a legal guarantee on the MSP among other issues.

Security remained tight at the Delhi borders with hundreds of personnel deployed at Singhu, Ghazipur and Tikri border points where the farmers have been camping.
