Earlier Boris Johnson told MPs that he was "leaving with my head held high"
Labour's Sir Keir Starmer attacked tax and spending pledges set out by Tory leadership candidates, but Johnson said their commitments are "very good"
The government will table a confidence vote in itself - due next week - after blocking a Labour bid
Prime Minister Boris Johnson says he feels "a real twinge" that this is "virtually the last time" he'll have an opportunity to answer questions from Ian Blackford.
He says the next leader of the Conservatives will want to work with the Scottish government "to protect and secure our union," adding "we are much, much better together".

Ian Blackford says all the candidates are "awful" and compared with them, "Genghis Khan looks like a moderate".

The PM has put the cat amongst the Conservative pigeons when he suggests this might be his last PMQs (it should be next week's) because his successor may be elected "by acclamation".
In other words, the final two candidates might reach a deal and avoid a vote of grassroots members.
This would be controversial to say the least, and some candidates are already asking their competitors to pledge to put themselves before the Tory membership.
Image source, House of Commons/PA WireThe outgoing PM responds by saying he feels everybody who has played a part in his government "has done a remarkable job in helping this country through difficult time".
Johnson says it is possible today's Prime Minister's Questions will be his last - "because the next party leader could be declared by acclamation".
He pays tribute to his time in office by saying: we got Brexit done; we delivered the first Covid vaccine in the world; and the UK led the world in helping the people of Ukraine.
He says all eight candidates for party leader will continue with the programme of skills and infrastructure expansion.
"It is true I leave not at a time of my choosing, but I am proud of the teamwork involved in all of those projects... and I'm also proud of the leadership I have given," he says.
"I will be leaving with my head held high".
It's Rishi Sunak, the former chancellor, who is in the line of fire next.
Sir Keir says he resigned last week criticising the PM and accusing him of not telling the public the truth - and next he's claiming he has a big plan to rebuild the economy.
He asks whether the PM can think of any job Sunak has had recently that may have meant he had responsibility for this "broken economy".

Sir Keir Starmer has taken a rather large political scalp - that of the PM himself. So now he tries to broaden the attack - with the new Chancellor Nadhim Zahawi in his sights.
And as predicted Boris Johnson is cheered to the rafters with calls for "more" from his own MPs when he says any of the candidates to replace him could "wipe the floor" with Starmer
Starmer accuses the Conservative leadership candidates of promising £200bn of tax cuts - twice the NHS budget.
But of course in reality there can only be one winner of the contest, and one set of tax cuts.
But Starmer feels he has been gifted an attack line from those candidates who say they will cut departmental budgets to pay for tax reductions.
Prime Minister Boris Johnson says this is "pitiful stuff from the party that voted against the £39bn which is necessary to pay for those 50,000 nurses" which will be recruited by 2024, he says.
Labour "don't have a leg to stand on" and the reason why economic growth was at 0.5% in May was because the UK exited from lockdown in May last year.
The Labour leader says the PM is "totally deluded to the bitter end".
He singles out new Chancellor Nadhim Zahawi - the "member for Stratford-on-Avon and Gibraltar", he quips - and his pledges of tens of billions of pounds in tax cuts and spending cuts.
Was the chancellor, Starmer asks, speaking on behalf of the government when he said this - and also said the government hadn't tackled the cost of living crisis?
The prime minister says he has been listening carefully to the leadership race - and that he thinks all the commitments so far are "very good".
He champions his government's record on policing numbers and new hospitals.
Johnson claims that Labour supports £94bn in extra spending - that would all be funded by extra tax. "That's the difference between them and us," he adds.
Next, Sir Keir asks about the contenders vying to become PM, who he accuses of acting like they've just arrived from the moon when it comes to tax promises.
Rather than desperately rewriting history, should they at least explain where they are getting all this extra cash from, he asks.

The government is tabling its own confidence motion.
It comes after it refused to allow time for a vote requested by Labour because of the wording of the motion.
A vote is expected next week.
“Labour were given the option to table a straightforward vote of no confidence in the government in keeping with contention, however they chose not to," said a spokesperson for the government.
“To remedy this we are tabling a motion which gives the House the opportunity to decide if it has confidence in the government.
“The government will always allow time for appropriate House matters whilst ensuring that it delivers parliamentary business to help improve people’s everyday lives.”
Prime Minister Boris Johnson says "to the best of my knowledge, everybody in this Parliament pays their full whack of tax in this country".
He says MPs should "cease this constant vilification of each other".
The UK is able to support people in the country more because of extra tax revenues, says Boris Johnson.
Labour, he says, are "happy to see people languish on benefits".
Starmer presses again on the tax rules.
He asks Johnson whether he agrees that all the leadership contenders should declare where they and their families are domiciled and whether they've been involved in offshore tax schemes.

Boris Johnson makes a quip at his own expense - he spoke of his liking for Welsh whisky. But he says he "ignored the revolver".
A reference to the fact he had tried to stay in office rather than shoot down his own political career when under pressure.
Responding to Starmer's question, Johnson says he is proud of the investment the UK attracts from around the world.
He says that he is "thrilled" by "offshore people investing in the UK".
He says it is possible Starmer is referring to one of the eight Conservative MPs vying to become the party's leader - and PM.
He says any of those eight candidates would "wipe the floor with Captain Crash-a-roony Snooze Fest".
Sir Keir Starmer tells MPs to cut the PM some slack as he's facing an "uncertain future and mortgage-sized decorators' bills".
He say he's going to ask a simple question next - does he agree that offshore schemes can pose a risk because some people use them to avoid tax they owe here?
Prime Minister Boris Johnson says "it's perfectly true that I'm grateful for the ability to speak my mind" which he said he "hadn't lost".
He says he's "committed to continuing the government of the country," and the first instalment of cost of living payment is "arriving in the bank accounts of eight million vulnerable people" tomorrow.
He says job vacancies are at an all time high.

The foreign secretary and chancellor are sitting next to Nadine Dorries, the culture secretary.
She has backed Truss to be Boris Johnson's successor. On the other side of Truss is deputy PM Dominic Raab
Raab has backed Rishi Sunak, seen by many as the frontrunner in the race. But the former chancellor has returned to the backbenche since quitting cabinet.
Image source, House of CommonsThe Labour leader opens up by jokingly welcoming the new Cabinet, though he says they will only be there for a few weeks.
He says now the PM is "demob happy", will he say what he really thinks and agree it's time to "scrap the absurd rules" around non-dom tax status?
Now the business of PMQs can get under way.
Boris Johnson says he is sure the whole house was saddened by the murder of the former Japanese PM Shinzo Abe and says his thoughts are with his family.
Sir Keir Starmer later echos those thoughts.
