What is 'Unlock 1' and why Congress isn't onboard with it?

Major relaxations have been provided in the first phase of Unlock 1. As per the issued guidelines, all the religious places, malls, and hotels will open from June 8 as the first phase of unlock 1 begins on this date. The Ministry of Home Affairs has issued the guidelines over Unlock 1 on Saturday. 
However, Congress leader PL Punia slammed the government's decision to curb the lockdown even as the Coronavirus (Covid-19) cases continue to surge.
