Senior Tories have refused to be drawn on reports that Prime Minister Boris Johnson is planning a major reshuffle and reorganisation of Government.
With Brexit scheduled for the end of January, speculation at Westminster has focused on a big shake-up of Whitehall.
Tory party chairman James Cleverly refused to confirm an anticipated Cabinet reshuffle would happen next month.
He said: "We already know that the Department for Exiting the European Union will be closing down, it has delivered on its mandate, the team there have done what has been asked of them, so there's going to have to be a degree of reorganisation.
"I don't know how extensive or otherwise any changes in Government will be."
And International Development Secretary Alok Sharma declined to comment on reports that his department could be merged with the Foreign and Commonwealth Office.
He told BBC1's The Andrew Marr Show: "There has been a lot of discussion in the papers. I think those matters are ultimately for the Prime Minister.
"What is absolutely, vitally, important is that we work very closely together."
He added: "In terms of development, if you look at the Conservative Party manifesto, it is very clear about the recognition of the value of the UK as a development super power."
