Sir — This refers to the editorial, “Zip it up” (April 24). At a time when BJP leaders are on a tough-lashing spree, commenting on anything and everything as if they have the authority to do so, it is good that Prime Minister Modi has come out openly to restrain them. Discipline within the party must be maintained. It will be a disaster for a party if partymen create a foot-in-the-mouth syndrome through media, more so, before parliamentary elections.
