Labour's Yvette Cooper has been elected to replace Keith Vaz as the leader of the Home Affairs select committee.
Hillary Benn was also appointed as the chairman of the Exiting the European Union Select Committee.
The appointments were announced by the Commons Speaker John Bercow.
Yvette Cooper has said Labour leader Jeremy Corbyn need to "show different ways of working" if he is to unite the party, as she called on his team to show "deeds not words".
Speaking on Peston on Sunday, the former Shadow Home Secretary said: "I think the thing that Jeremy needs to do in order to pull the whole party together is to show different ways of working, for example to have shadow cabinet elections that would allow a lot of people to come forward and to stand.
"But also some other things that he and John (McDonnell) need to do to show through deeds not words that actually they want to take the lead in drawing the whole party together and... making sure we can win back votes in marginal seats that we need."

Labour MP Yvette Cooper has said Labour are "hanging on" in some parts of the UK following last Thursday's election, and it's "not enough".
Despite Sadiq Khan winning the London Mayoral election, Labour lost 18 councils in England, 13 in Scotland and one in Wales - a result that has led to criticism of Jeremy Corbyn's leadership.
Reacting to shadow chancellor John McDonnell's comments that Jeremy Corbyn's critics should "get behind us and stop carping", Cooper said the party should be "honest" about Labour's position, and "how far" they have to go.
The Labour MP accused the prime minister of "putting this House and this country to shame".Read the full story ›
Labour's Yvette Cooper admitted that while her party were in government the pace of immigration to the UK was "too fast".
She told the BBC's Andrew Marr Show that Labour should have implemented "transitional controls" on Europe and that there is "concern about immigration across the country".
But she said that reform on immigration was only possible if Britain remained in the EU.
If we want to change the rules then you actually have to be in [the EU] in order to argue for that and to argue for reform. You can't get reform if you just stay on the outside.
The former Shadow Home Secretary appeared to contradict Labour leader Jeremy Corbyn who said that he did not think too many migrants had entered the UK when he announced his support for the Remain campaign in the EU referendum.
