While we have lately heard much of how the EU will not dare to push Britain around because we are “the fifth largest economy in the world”, rather less notice has been paid to the fact that, since the post-Brexit fall in the pound, we may already have been replaced as the fifth-largest economy by India.

Indeed India’s GDP is growing so fast that by the 2030s, analysts predict, it could be larger than that of the entire EU, and by 2050 could in PPP terms be surpassing the US and China as the largest in the world. Rather more coverage was given to the dreadful pall of pollution which last November engulfed India’s capital Delhi for 10 days.

My son Nick, who lives there with his Indian wife and one-year old daughter, posted a chilling video on Facebook, showing how, against the official “safe” pollution level of 30 parts per million, London was registering 117 and the notoriously smog-ridden Beijing 360. But inside their Delhi flat, with air purifiers, the level was a staggering 960, and outside on their balcony it shot off the scale at 1,248.
