Mr Lancaster made the announcement on Twitter, adding that "it's a real privilege to work with the outstanding servicemen and women who give so much to our country."
It comes as Prime Minister Johnson continues to make further ministerial appointments this evening.

We don’t always agree in politics but his passion for the armed forces has always shone through."
