It’s curious why the Indian foreign office has never sent a Sikh as high commissioner to Pakistan. Nor for that matter, an ethnic Tamil diplomat to Sri Lanka. The latter is probably because India would have wanted to avoid antagonising the ethnic Sinhalese in that country who fought a bloody 30-year war against the Tamil Tigers. But since the war has been over for quite some time, is there any need for old practices to persist? In the case of Pakistan, no Sikh has been sent because of the Khalistan factor. But again, that’s history.
