Prime Minister Boris Johnson will address his new intake of Conservative MPs later as they arrive in Westminster to take their seats in Parliament.
Many of the 109 new MPs won in areas traditionally held by Labour in Thursday’s election, which saw the Conservatives gain an 80-seat majority.
Their first job will be to vote on the Withdrawal Agreement Bill that the PM intends to bring back before Christmas.
Mr Johnson is also expected to carry out a mini cabinet reshuffle and he needs to fill posts made vacant by those who stood down ahead of the general election, including the culture and Welsh secretary posts.
The Queen will formally open Parliament on Thursday when she sets out the government’s legislative programme.
