Britain is still struggling to get a proper test-and-trace system in place. It’s struggling in many ways. As James Harding’s and Matthew d’Ancona’s essays have made clear this week, the Johnson government’s response to the pandemic has been characterised by dysfunction and delay.
But what if a test-and-trace system had been set up several weeks ago? And set up in Westminster, the corner of London where Britain’s leading politicians ply their trade? What it would have shown is a virus in full flow, moving from tightly packed MPs to advisers to ministers… and eventually to the prime minister himself.
In the absence of that system, here’s the next best thing: a timeline of Covid-19’s procession through British politics. Number 10, it turns out, had its own R number – and a high one.
“There is a lot of Covid-19 in Westminster”
Thursday 5 March
Boris Johnson hosts an event for International Women’s Day at Downing Street. One of the MPs in attendance is Nadine Dorries, a health minister. Dorries first showed symptoms of Covid-19 on this day.
Wednesday 11 March
Nadine Dorries tests positive for Covid-19, becoming the first member of Parliament to fall ill with the virus. Multiple MPs who had been in close contact with Dorries are asked to self-isolate. Rishi Sunak delivers his Budget statement to a packed chamber.
Friday 13 March
11 MPs entered self-isolation after coming into contact with Dorries, among them Anne Marie Trevelyan, the international development secretary and a member of the Cabinet. She says that she had self-isolated but returned to work after testing negative for the coronavirus. Increasing numbers of MPs call for Parliament to close to stop the spread of the virus.
Monday 16 March
Boris Johnson makes a statement encouraging people to work from home where possible. The majority of civil servants move to working from home following the announcement. Neil Ferguson, the government’s adviser on epidemiology, attends a press conference at Downing Street. The government held its first daily press briefing on the coronavirus on this day.

Johnson chairs a meeting on the coronavirus from self-isolation, “full of vigor” according to Dominic Raab. A Number 10 spokesman says that Johnson is still fully able to run the coronavirus response and is chairing daily meetings. Johnson confirms this by tweeting a photo of himself chairing a meeting. Reports later emerge that sources at Number 10 said the PM was “coughing and spluttering his way through conference calls”.
Daily briefing delivered by: Raab

Thursday 2 April
A week after he fell ill, a Number 10 spokesman says that Johnson “continues to have mild symptoms, but he does still have symptoms.” Johnson appears on the steps of 11 Downing Street to clap for carers and in a video message announcing a plan to ramp up testing.
Despite Downing Street’s reassurances to the press that Johnson would be back to work within days, by 2 April his doctors were concerned that the prime minister’s condition was in fact deteriorating, according to The Guardian. St Thomas’ hospital begins preparations to admit Johnson. Staff there are informed that he is more severely ill than has been publicised and that he might need oxygen.
During the night, Cummings’ son is ill so the couple “took medical advice which was to call 999”. The child is taken to hospital by ambulance.
Hancock, who had tested positive for the virus only a week before, returns to work.
Mark Sedwill, the Cabinet secretary, had coronavirus symptoms around this time too, but this was not reported until 14 May. On 27 March, reporters had asked the Cabinet Office whether Sedwill was infected. They said he wasn’t. They claim they did not lie to the press as he had no symptoms at that point. According to Sky News, Sedwill was last pictured in the Cabinet room on 31 March. At that point, he may have had the virus but not yet have been displaying symptoms. Pictures released by the government show him back in Downing Street on 28 April.

Obviously that is beginning to slow down his recovery. He needs to go to bed.” According to The Guardian, Symonds became distressed at the situation: she was “agitated” and “crying down the phone” to friends.

At the daily press briefing, Raab confirms that Johnson is still in charge and that he is in hospital only “as a precaution.” However, Raab admits he has not spoken to Johnson since his hospital admission.
The optimistic picture painted by Johnson’s aides and his Cabinet belies the severity of his illness: later that day Johnson is moved to intensive care as Downing Street reveals his condition has “worsened”. He is on oxygen but not a ventilator. Chris Whitty leaves self-isolation.

Daily briefing delivered by: Raab
Friday 17 April
Reports in the media suggest decisions are not being made in the absence of the PM. A government source tells the Daily Telegraph that there is no plan for exiting lockdown because “there can be no exit strategy until Boris is back in business”.
Grant Shapps, the transport secretary, gives a different reason for the delay, saying that there could be two more weeks until the UK gets greater “clarity” on what will happen next as scientists will examine the UK’s progress on the virus at the end of April. Johnson’s spokesman says it is “just wrong” to imply that the Cabinet is waiting for the PM to return to make decisions on lockdown.
Another Cabinet source tells the Telegraph: “There’s no exit plan at the moment because they don’t want to do anything without the boss’s say so. “Not a huge amount is going on in these Cabinet meetings.”
