Meanwhile, former prime minister Tony Blair has been accused of breaching quarantine rules after being pictured at a restaurant in London reportedly 10 days after visiting Washington DC. The Sunday Telegraph says he has been accused of failing to self-isolate for the full two-week period that is required after travelling to the US for a two-day trip on a private jet. A spokeswoman for Mr Blair said Whitehall officials had told him to follow guidance for international conferences “which he did”, adding the former PM had been tested, before during and after the trip.
