Congress leader Shashi Tharoor reacted to the new UK vaccine rules requiring fully vaccinated travellers from India to quarantine and called it “double standard”.“The double standards applied by UK are impossible to understand. I personally don't have time to go to a country and sit in quarantine for 10 days. So I have cancelled my trip. It's time we all stood up and said to the British - 'Get your act together'. Either you ask Serum Institute of India (SII) to make those vaccines and ship it to Britain or you say you don't accept the vaccines. You can't have it both ways”, said Shashi Tharoor to ANI.
