Mims Davies has left her post as Minister for Civil Society, but who her successor will be remains a mystery.
Davies, who became Minister for Sport and Civil Society in November, announced on Twitter on Friday she had been appointed as a parliamentary under-secretary of state at the Department for Work and Pensions.
The Eastleigh MP also tweeted that she wished Matt Warman, who was announced as a new minister at the Department for Digital, Culture, Media and Sport last week, "great success".
But neither Warman, a former technology editor at The Daily Telegraph who became the Conservative MP for Boston and Skegness in 2015, nor any of the other three DCMS ministers has yet been allocated the charities brief.
Besides Warman, the other DCMS ministers are Nigel Adams, Baroness Barran and Rebecca Pow. No other ministerial appointments are expected at the department.
All four report to Nicky Morgan, the newly appointed Secretary of State for Digital, Culture, Media and Sport.
A DCMS spokesman confirmed Davies' departure, but said ministerial responsibilities at the DCMS were still being decided and would be announced "in due course".
He added: "I cannot say how it is going to work out at the moment."
Adams announced last week that he had been allocated responsibility for sport, but there has been no word yet whether this would also include civil society, as it did under Davies.
Davies tweeted that she "truly loved" her charities brief, but her biography on the social media site does not mention her time overseeing civil society, although it does say she is a former sports minister.
Senior voluntary sector figures expressed frustration last week about the sector being "near the very end of the queue" after a government reshuffle.
Today Sir Stuart Etherington, chief executive of the National Council for Voluntary Organisations, paid tribute to Davies.
"Mims has been an energetic and dedicated Minister for Civil Society," said Etherington.
"Taking on the brief not long after the launch of the government’s Civil Society Strategy, she made the time to listen to and collaborate with the sector to move its ambitions forward. We wish her luck in her new role at the DWP.
"We look forward to working closely with her successor at DCMS to continue her good work."
