There has never has been a weaker Prime Minister's Office even though all functions are centralised, former union minister and BJP leader Arun Shourie has said. "You centralise the functions but do not have either the domain expertise or the authority... then things get stuck," Mr Shourie, a one-time admirer of Narendra Modi, said on Monday at an event moderated by NDTV's Sreenivasan Jain. The 73-year-old also said that people "were beginning to miss" former prime minister Manmohan Singh who was present in the audience.
