Even this challenging situation would ease
In Telangana, as far as my knowledge goes there are two Dy. CMs are there. But KTR. son of the CM is more powerful than him.
It is the head of the government who decides about his ministers, their roles and responsibilities. If PM wants he can have a person designated as Dy PM. In the absence of PM, the DY PM may lead the government. Otherwise, the senior minister in the ministry will be given the responsibilities of PM.
Earlier also there were some PMs under whom there is no deputy PMs. As far as my remembrance goes there was no Dy PM when Manmohan Singh was the PM. There was no DyPM during the 3rd time ruling of Indira Gandhi.
If the PM wants he can designate somebody as Dy PM. Probably Modiji felt that there is no necessity.
Knowledge is power.
