David Cameron is in the United States visiting Barack Obama today, so his place at Prime Minister's Questions will be taken by Nick Clegg.
The Lib Dem leader will face Labour's deputy leader Harriet Harman across the Despatch Box but it is not just opposition MPs who will be enjoy baiting the deputy prime minister.
Tory backbenchers are also likely to seize the chance to take a swipe at their coalition partner. Rubbing his virtual hands with glee on Twitter, Douglas Carswell mused "what a target rich environment" the Commons would be today.
See how Clegg handles the half-hour session below:
|@ TimMontgomerie : Hostile #PMQs to Clegg from Tory backbenchers: Redwood on regulations, Lilley on Lords reform, @DouglasCarswell on child benefit|
|@ JoeMurphyLondon : Also interesting how many Tories are tweeting praise of Clegg #pmqt|
|@ trsmith87 : Best PMQs for a while. Proper knock about. #pmqs|
|@ dylsharpe : Unmemorable #PMQs. Clegg did well to repel the qus, when not angry. Harman good at condemning, but may regret tactic of slaughtering the LDs|
|@ Lobbydog : Clegg doesn't even pretend to sidestep the NI question from Skinner. Just completely ignores it. #pmqs|
|@ jamesrbuk : An unusually even-tempered intervention from Dennis Skinner there. Or not. #pmqs|
|@ georgeeaton : Clegg says boundary changes are a cause close to the Tories' heart. Hint that it's not close to his? #PMQs|
|@ AnushkaAsthana : Harriet Harman says only thing Clegg stands up for is when the PM walks into the room. BOOM BOOM! #PMQs (Clegg getting angry - love it!)|
|@ GraemeDemianyk : Tory Cabinet ministers Gove, Spelman and Lansley standing in shadows at #pmqs not looking entirely convinced by the Clegg show|
|@ JohnHigginson : Clegg's fourth outing at PMQs is his best yet. Harman's got lots to throw at him but nothing sticking. #pmqs|
|@ EmmaFrancesCarr : Clegg is doing really well. Surprisingly well. #pmqs|
|@ amyelizjackson : Hattie H sounds less shrill than usual. Maybe she learned something from The Iron Lady. #dpmqs|
|@ James_Macintyre : Bizarre: Clegg attacking Labour from the left on NHS privatisation while sitting with Tories.|
|@ toadmeister : @EdBallsMP seems remarkably subdued. No flatlining hand gestures. Has Harriet Harman told him to rein it in? #pmqs|
|@ TimMontgomerie : I always get the feeling that Labour's attacks on Cameron are business but when they go for Clegg it's personal #PMQs|
|@ openurmindnsee : balls has written harman questions, yes? #pmqs|
|@ JohnHigginson : Harman kicks off with unemployment saying women are hardest hit. Clegg (doing very well so far) says went up under Labour by 20% #pmqs|
|@ alexforrestitv : Liz Kendall asks Clegg what went wrong with our economy. He says Labour Govt. #pmqs|
Labour MP Liz Kendall kicks off the questions by asking "what's gone wrong" with the economy.
Clegg says what went wrong "was the Labour governments for thirteen years creating the most unholy mess in 2008".
|@ joncraig : Full house for Clegg PMQs on LibDem benches below gangway too. Whole House pretty packed despite PM away in US. Lots of LibDem MPs rising!|
|@ HumeBrophy : Cameron’s spokeswoman tells The Sun’s Whitehall Correspondent "I'm sure the Deputy PM is more than qualified to fill [his] shoes at #PMQs”|
|@ joncraig : LibDems out in force for Clegg PMQs. Danny Alexander & Michael Moore in plum seats on front bench, edging out Ken Clarke & Philip Hammond.|
|@ PoliticalYeti : Cringing already and #PMQs hasn't even started. Fear the DPM will take a hammering from all sides.|
|@ worgztheowl : Lucky for @Ed_Miliband that Dave's away, he'd have so much to go on he wouldn't know what to ask first. #pmqs|
|@ petermbarrett : Willing to bet #Harman tries a 'gag' around #Cameron having been at a baseball game. Something about Coaltion 'swinging and missing' #pmqs|
|@ JonNarcross : Always worth tuning in for... RT @cptjamesmartin The legendary Dennis Skinner MP due to speak on #PMQs at 12:00|
