George Osborne will have an opportunity to impress his fellow Conservative MPs and give them a sense of what he would be like in Number 10 as he steps in for David Cameron at prime minister's questions (PMQs) on 9 December.
The Chancellor, who is tipped as a future Tory leadership contender, will take on Labour's shadow first secretary of state Angela Eagle across the dispatch boxes. Cameron is absent as he continues his EU renegotiation in meetings with the leaders of Poland and Romania.
Osborne first took PMQs in this parliament in June when he verbally sparred with Labour's shadow foreign secretary Hilary Benn, who has since seen his stocks rise after an impassioned pro-Syrian air strikes speech in the House of Commons. The 30-minute-long grilling has recently seen a new flavour of questioning after Jeremy Corbyn was elected Labour leader in September.
The left-winger has fielded direct questions from the public to the prime minister. Westminster watchers will be keeping a close eye on Eagle to see if she adopts Corbyn's direct democracy drive or keeps with a more traditional and adversarial method.
Storm Desmond, which left parts of the north of England and the Scottish borders flooded, is expected to come up during the session and Osborne's welfare cuts, following Osborne's embarrassing tax credits climb-down, is another likely subject for PMQs.
You can watch all of the Commons action from 12:00 GMT on BBC Parliament, Parliament TV, BBC 2's Daily Politics and Sky News. Also make sure to follow @IBTUKPolitics for live updates, reaction and commentary.
