Theresa May'scabinet reshuffle will see her seek to bring in new faces to her ministerial team in a bid to inject "youth, energy and fresh thinking".
In the past two months, as well as losing Mr Green, the PM has also seen defence secretary Sir Michael Fallon quit amid allegations around his conduct and Priti Patel resign as global development secretary after a row over unauthorised meetings with Israeli officials.
Speaking on the BBC's Andrew Marr Show on Sunday morning, she refused to be drawn further on details of the shake up.
At one point past year, there was speculation that May would possibly move Boris Johnson, the foreign secretary, into a beefed-up business department with responsibility for Brexit planning, but that idea seems to have been dropped in response to opposition from Johnson.
According to 10 Downing Street sources, top ministers Philip Hammond, Boris Johnson, Amber Rudd and David Davis are safe, although the same can't be said for Education secretary Justine Greening, who is expected to lose her portfolio.
There's always been talk of a cabinet reshuffle and now Mrs May is finally going through with it - albeit she has been pushed into it because she had to sack her second-in-command Damian Green over porn allegations - which has left a gap at the top table.
In a clear hint that Greening is out of favour, Nick Timothy, May's joint chief of staff until the general election and her closest policy adviser over the last decade, used his column in the Sun last month to deride Greening's record, saying Greening's social mobility action plan was "full of jargon but short on meaningful policies" and that "it would have been better left unpublished".
It is known that Sir Patrick McLoughlin, widely blamed for the Tories' poor general election performance in June, is to step down as Conservative Party chairman.
Ms Greening, along with Business Secretary Greg Clark and the Leader of the Commons Andrea Leadsom, are thought to be vulnerable, but could be shuffled to new jobs rather than sacked. However, it is unclear whether that person will also inherit Green's job as first secretary of state (de facto deputy prime minister) because that is effectively a courtesy title and prime ministers often do without one.
Health secretary Jeremy Hunt ha been touted to replace Green, although reports have suggested that May might prefer not to move Hunt in the midst of an NHS winter crisis.
Mr Hunt, who has been health secretary for more than five years, was a remain supporter during the referendum but has been critical of the EU's approach to the negotiations since then and has said warnings about the economic damage of leaving the European Union have so far been over-stated. Raab, a leading Brexiter, would replace Brandon Lewis as the immigration minister, the report said.
'Regardless of who leads us into the next Election, it is very much the duty of today's leader to pay attention to fixing our rusty party machine'. "I'm not a quitter", she said. "I've said I want to fight that".
"I'm in this for the long term", May told the BBC, adding "obviously I serve as long as the people want me to serve".
