After the Centre's open rebuke for Delhi Chief Minister Arvind Kejriwal over his tweet on a "Singapore strain", the Aam Aadmi Party (AAP) raged at the ruling BJP saying it "is worried about Singapore while Mr Kejriwal is worried about children". Singapore formally objected to the Delhi Chief Minister's tweet on a "new Singapore variant" that is "very harmful to children", the central government said, adding that the Indian envoy told the country Mr Kejrwal had "no competence" on Covid variants.
