Amber Rudd MP has been named the new right-hand woman to the Chancellor.
She has been appointed the new Parliamentary Private Secretary (PPS) to George Osborne.
Ms Rudd said: “I am thrilled. I will be working closely with George Osborne, going to Treasury meetings and making sure he knows what MPs are thinking.
“My role will be to liaise between the Secretary of State and House of Commons.”
A PPS is appointed by a minister to act as an unpaid assistant.
It is often seen as a stepping stone towards an MP being given a junior minister or cabinet post.
Commenting on the PPS appointments this week, Conservative Party Chairman Grant Shapps said:
“These are some of the brightest and the best of the Conservative Party and their appointments are testament to their hard work and dedication.”
