Last December, The Times reported that he was among senior officials to attend a lockdown Christmas quiz in December 2020, though Downing Street denied the allegation.
Before being head-hunted for Johnson’s team, Mr Rosenfield worked as a Treasury official for 10 years, during which he served under Labour prime minister Gordon Brown, chancellor Alistair Darling, and Darling’s Tory successor George Osborne.
After a decade at the Treasury, Mr Rosenfield went first to Bank of America/Merrill Lynch, and latterly to Hakluyt, a strategic advisory firm founded by former officials of MI6, the secret intelligence service.
As chair of WJR, Mr Rosenfield had a seat on the Jewish Leadership Council.
Mr Johnson is also expected to put forward the former Culture Secretary and author Nadine Dorries and Scotland secretary Alister Jack for the House of Lords, along with several other of his former Downing Street aides including two under the age of 30.
Those on Johnson’s resignation list will be subject to a vetting process before they become peers, and if they’re all approved, the former PM will have created more than double the peerages of his predecessors David Cameron and Theresa May.
