All India Radio, unsurprisingly, is a tireless promoter of the PM's Mann ki Baat. At this year's India International Trade Fair AIR has a stall on the theme of MKB, which is a big tourist draw, we are told by DD News. People are queuing up at the stall to drop their suggestions for the forthcoming edition of Mann Ki Baat, in a large box placed at the stall to collect letters addressed to Prime Minister. This PMO certainly knows how to deploy the public broadcaster.
