The main image on the Guardian is Prime Minister Rishi Sunak and his wife, Akshata Murty, meeting schoolchildren in Delhi before the G20 summit. Sunak is also the subject of the lead story, with calls by a group of MPs for the PM and health secretary not to restrict Covid vaccines to those aged 65 and those in vulnerable groups. It comes amid concern that the new Pirola variant of the disease could put pressure on the NHS this winter.
