We need to pass five tests before we can think about moving on to the next phase in the coronavirus response. We are not there yet," the spokesperson told reporters."What we need to be focused on is everybody following the social distancing rules and ensuring that we have got the spread of this virus fully under control."In recent weeks, critics have accused Johnson's government of failing to provide key workers with an adequate supply of personal protective equipment.The UK held a minute's silence on Tuesday for all front-line workers who have died from the coronavirus.As clocks struck 11:00, senior political leaders, including Johnson, joined hospital and nursing home staff in observing the silence.London's underground and bus networks came to a halt as workers honoured colleagues, and Westminster Abbey paid tribute to "the sacrifice of health and care workers who have lost their lives in the service of others".On Monday, Health Secretary Matt Hancock said 82 workers in the National Health Service and 16 social care staff had died so far.
