UK Prime Minister Boris Johnson told his ministers and advisers his main concern in easing restrictions would be a potential second wave of coronavirus, a government source told CNN.

Johnson expressed his concern during a two-hour Zoom video call with his team on Friday from the UK Prime Minister’s country residence, Chequers, where he is recovering from the virus.

On Monday, Johnson’s spokesperson said a potential second peak “is ultimately what will do the most damage to health and economy. If you move too fast you risk a second peak. The public will expect us to protect life. If you have a second peak, it’s not just damaging for people’s health but would end up in a second lockdown which would be damaging on the economy.”

He said the government will be “guided by the science” in terms of when to lift social distancing measures.

The UK government could however potentially relax some coronavirus restriction measures and strengthen others, when it comes to a second review of the current lockdown, the spokesperson said.
