The Congress Tuesday claimed that Prime Minister Narendra Modi's public relation machinery was "working overtime" for the 100th episode of his monthly radio address 'Mann ki Baat' while accusing him of being silent on crucial issues such as Adani and China.

The 'Mann Ki Baat' programme is set to complete its 100th edition next Sunday, with the prime minister saying it was public support that led to the success of his monthly radio address.
