Sir Keir says that Germany has a working app which has been downloaded 12 million times..

"We spent £12m on this," he says and asks: "When are we going to have a working app?"

"He is completely wrong," hits back Boris Johnson.

He repeats that no country has a working contact tracing app and says the UK's test and trace operation is already up and running.

"It will be indispensable to our future success," he says before asking the Labour leader if he thinks schools should be reopened.

Sir Keir Starmer says the UK's delayed contact-tracing app is the only known way to trace unknown contacts.

He accuses the government of now downplaying the importance of the app, having previously described it as "critical".

PM Boris Johnson replies that "not a single country in the world" has managed to put in place a "functioning app".

He says test and trace has been "very successful" - and accuses Labour of "yo-yoing" on the issue of lockdown.

"65,000 people have lost their lives because of Covid-19," says Sir Keir Starmer

"The PM should welcome challenge that could save lives rather than complaining about it," he says.

He now turns to council finances noting that eight out of ten face bankruptcy.

He asks the PM when local authorities will get the guidance they need about implementing local lockdowns.

Boris Johnson replies that the government has "a very effective cluster busting operation".

He adds "I'm not going to pretend to him that this thing is beaten," and emphasises the need for vigilance.

Sir Keir Starmer says the PM did not address his point about the people who weren't contacted by the test and trace system.

He asks what the government's strategy is for closing the gap between number of people contacted and estimated cases.

He says the PM risks "brushing aside" the challenge and underestimating the risks.

In reply the prime minister accuses the Labour leader of giving an "false impression" of the system.

He says the system has managed to contact the "vast majority" of those who actually test positive.

Sir Keir Starmer begins his questioning of the PM by suggesting that if the plan to reopen the country "is to work we need an effective track, trace and isolate system".

He says "the PM promised a world beating system would be in place by 1 June".

He says that only 10,000 of the 33,000 estimated to have coronavirus have been reached.

He praises the work done so far but suggests this is "a big problem".

"He has been stunned by the success of the test and trace operation," replies Boris Johnson.

The PM adds that the system has "got up and running much faster than the doubters expected".

Here are some of the stories from around the UK this morning – they may provide some clues to what Boris Johnson could be asked about at PMQs.

• Health leaders are calling for an urgent review to determine whether the UK is properly prepared for the "real risk" of a second wave of coronavirus.
• This follows the PM’s announcement that swathes of coronavirus lockdown measures will be relaxed in England from 4 July.
• Guidance has been published on how hairdressers, hotels, pubs and other businesses in England can reopen safely.
• Scotland's first minister Nicola Sturgeon is expected to give an update on the timescale for easing the country's lockdown restrictions today.

Other subjects that may also come up include the government's test and trace programmes, the reopening of schools and the possibility of opening air bridges with other countries.

The lecterns emptied, the lights were turned off, the union flags left hanging behind the grand double doors of the Downing Street room that's staged nearly a hundred briefings in the last few torrid months.

The prime minister's announcements about how England will take a big step out of lockdown came pretty much as billed.

The tensions between the political desire to move on and the scientific judgements of what's best to protect life were extremely clear. The government's top scientists and medics used almost every opportunity to urge caution and restraint.

And so in the coming days we enter as a country, a strange half world where the intensity of the dangers from the virus have faded, but not disappeared - not normal life, as we know it, back with comforting familiarity, but a new, ever-stranger normal where the public and our politicians must remain on guard.

And later in the afternoon Labour will attempt to force Housing Secretary Robert Jenrick to publish all documents relating to a controversial planning decision, during an opposition day debate.

There will also be a debate on testing NHS and social care staff.
