Prime minister’s questions: a shouty, jeery, very occasionally useful advert for British politics. Here’s what you need to know from the latest session in POLITICO’s weekly run-through.

What they sparred about: Keir Starmer escaped from all his domestic troubles by jetting off to China, so Deputy Prime Minister David Lammy was left to fend off questions from disgruntled MPs both in front of (and behind) him. Tory Leader Kemi Badenoch carried on rotating which frontbencher batted for the Conservatives, handing that dubious honor to Shadow Business Secretary Andrew Griffith. Given his brief, er, business rates dominated.

Hold my beer: Griffith led on the government’s U-turn watering down business rate costs for pubs, asking Lammy to confirm that more than 90 percent of “retail, hospitality and leisure businesses will get nothing.” The deputy PM, you may not be surprised to read, swerved that interrogation and said it is “always a pleasure to hear from the co-author of the mini-budget” — Liz Truss’ economic proposals, which led to her swift departure from No 10.

Drink: The PM may be out of the country, but it wouldn’t be PMQs without a mention of Britain’s shortest serving prime minister — the person Labour thinks is still the Tories’ biggest electoral liability nearly three-and-a-half years after she left office.

Last orders: The shadow business secretary bigged up his experience, unsurprisingly, in business, contrasting that with Lammy’s 25 years “manufacturing grievance.” Nonetheless, Griffith claimed the help is “too little, too late” with striking visual imagery, arguing “our high streets are bleeding out and the chancellor’s handing out a box of sticking plasters.”

Out of the till: Lammy may have had little notice that Griffith was stepping into the blue hot seat, but his aides did their homework. The deputy PM ripped into Griffith opposing the minimum wage.

Best of enemies: Griffith had plenty of barbs up his sleeve too, labeling his opposite number “left behind Lammy” for not getting a cushty trip to Beijing. But the already depleted Tory benches were even quieter than usual, making it harder for the PMQs novice’s lines to land.

That said: He managed a good line about “Andy from Manchester having his dreams crushed by Labour,” a reference to the Greater Manchester mayor getting blocked from standing in the Gorton and Denton by-election over fears he might challenge Starmer for the top job (though, of course, Labour would deny that). “It is our party that is getting stronger,” Griffith cried unironically to shrieks of laughter from the government benches. Indeed, the polls beg to differ.

Crossing the line: As usual with these exchanges, the substance of support (or lack thereof) for businesses was lost after about question two. Lammy concluded his responses by highlighting that Badenoch praised the art of queuing during her appearance on the long-running BBC “Desert Island Discs” radio program. It was too easy for Lammy to argue Tory MPs took her at her word after three defections just this month.

Helpful backbench intervention of the week: Rugby MP John Slinger continued meeting his ultra-loyalist stereotype by commending Labour’s record on the NHS and slipping in criticism of Reform’s health policies. Lammy couldn’t have been happier, joyously reiterating the point made by every Labour politician that the NHS is only safe under them.

Totally unscientific scores on the doors: Lammy 8/10. Griffith 6/10. It was unsurprising for the Tories to lead on a U-turn, given there were many to choose from. However, despite business rates being Griffith’s area of expertise, he did not make his point land. Good lines from both sides meant the session became a battle of which voices could shout the loudest. Given the government’s parliamentary majority, there could only be one winner.
