Select committees are cross-party groups of MPs tasked with scrutinising the actions of government and its ministers; the transport committee has oversight for aviation, cruise and rail, among other sectors.

Conservative MP Merriman, who has been a prominent supporter of the travel industry throughout the Covid pandemic, will relinquish his chairmanship of the committee to focus on his new role at the DfT.

Select committee chairs are allocated according to party, with transport falling to the Conservatives meaning only a Conservative MP can stand for the role, although all MPs can vote.

Nominations will close at midday on Tuesday 15 November. In the event there is just one candidate, the result is likely to be announced the same day. If there are multiple nominations, a ballot will be held on Tuesday 16 November with the result likely to be announced the same day.

Candidates require 15 signatures from their own party to secure their nomination.
