As had been expected, Armed Forces minister James Heappey has just confirmed he has resigned from the role.
He said he had "loved every minute" as Armed Forces minister, adding: "Our Armed Forces and Ministry of Defence civil servants are the very best of us.
"Representing them in parliament and around the world over last 4.5 years has been an amazing privilege."
Mr Heappey added: "My sincerest thanks to all who serve so brilliantly in our nation's Armed Forces and to the families that stand behind them.
"We're asking a lot of them at the moment - rightly so, the geo-political situation demands it - and we should never forget their sacrifice."
It comes a day after he called for the government to spend more on defence, as it continues to fall short of the 2.5% of GDP - or even more - that many Tory MPs have been calling for.
Robert Halfon, the Conservative MP for Harlow, has confirmed he is resigning as the minister for apprenticeships and skills today.
He will also step down as an MP at the next general election.
The MP's resignation follows hot on the heels of the departure of Armed Forces minister James Heappey, who quit his role minutes before (
see 16.00 post).
Mr Halfon said: "After well over two decades as the Harlow parliamentary candidate and as MP, I feel that it is time for me to step down at the forthcoming general election, and in doing so, to resign as a minister in your government."
This means more than 60 Tories have now confirmed they will not stand at the next general election.
And, as our
chief political correspondent Jon Craig says, there has been some suggestion "that this number could rise".
