Baroness Manzoorhas stood down as a Government whip in the Upper House just over a year after taking up the position.
A Downing Street spokesman said: "Baroness Fairhead and Baroness Manzoor have resigned from the Government for personal reasons.
"The Prime Minister thanks them both for their service in their roles at the Department for International Trade and the Whips' Office respectively.
"Their replacements will be announced in due course."

She entered the House of Lords with a life peerage on her appointment as a minister in Liam Fox's Department for International Trade in 2017.
Former Legal Services Ombudsman for England and Wales Zahida Manzoor entered the House of Lords in 2013 as a Liberal Democrat peer.
She was then the party's work and pensions spokeswoman under the leadership of Tim Farron.
