Amartya Sen, a Nobel Prize-winning economist now resident in the US, told The New Yorker magazine that his friends are reluctant to criticise the government on the phone, adding, “People are afraid. I’ve never seen this before.”

Alarmed by the increasingly compliant judiciary (and much of the media), Pratap Bhanu Mehta, an eminent Indian academic, has written that: “The noose is tightening around all independent institutions in India.”

Mr Trump and Mr Modi are ideological soulmates. They are both assertive majoritarians, scornful of liberal concerns with minority rights.

They have promised to crack down on illegal immigration and have stoked fears of Islamic extremism — partly as a way of consolidating their political base.

Mr Modi’s many defenders argue that one of his great strengths is that, like Mr Trump, he is in touch with “the common man” — he cares little for the opinions of urban elites.
