Rosenfield worked at
HM Treasury from 2000 to 2011. From July 2007 to April 2011 he worked as principal private secretary to
Chancellors Alistair Darling and
George Osborne during and after the
2008 financial crisis. Rosenfield then left public service to join
Bank of America Merrill Lynch as a managing director in investment banking from June 2011 to March 2016. The bank subsequently bid for lucrative roles advising
UK Financial Investments on the sale of
Northern Rock, which had been the subject of oversight by the Treasury while Rosenfield had been in office. In April 2016 he became a partner at
Hakluyt & Company, a corporate strategy adviser.
Downing Street Chief of staff On 26 November 2020 Downing Street announced that Rosenfield had been appointed as the
Downing Street Chief of Staff, and that he would formally take office on 1 January 2021. Shortly after his appointment, in April 2021, Rosenfield was implicated in a potential lobbying scandal in relation to the proposed
European Super League of major football clubs. Rosenfield met with Manchester United chief executive
Ed Woodward in Downing Street on 14 April, at the height of debate about the scheme and whether it would receive support from the government, apparently also introducing Woodward to Johnson at the meeting. Rosenfield reportedly told Woodward that Downing Street would not oppose the controversial plans, from which Manchester United and Woodward stood to benefit financially. Downing Street sources subsequently denied that the scheme was discussed at the meeting. Woodward had also allegedly tried to keep the meeting secret. In July 2021 it was reported by
The Times that Rosenfield's leadership was unpopular among some Downing Street staff members, including
Nikki da Costa, the director of communications. There were suggestions that Rosenfield had failed to hold strategy meetings for political advisors for up to six months. It was additionally reported that Rosenfield did not frequently chair Downing Street staff meetings, despite his role as chief of staff, instead leaving them to his deputy
Simone Finn. It was reported in
The Sunday Telegraph in January 2022 that Rosenfield had attended a cricket game three days before the
Fall of Kabul, for which the UK government was criticised in its response. Downing Street did not deny the allegations but stated that "Dan was in constant contact with the office". In December 2021 Downing Street denied speculation in a report in
The Times that in December 2020 Rosenfield had
attended a Christmas party in the office of
Simon Case, the head of the
Civil Service, when
British public health restrictions as a result of the
COVID-19 pandemic forbade such gatherings. Speculation arose that Rosenfield might be sacked by Johnson for his role in the controversy, amid further criticism that he had presided over a
'laddy' culture within Downing Street which had excluded female members of staff. Rosenfield resigned as Downing Street chief of staff in February 2022 following the resignation of
Munira Mirza during the
Partygate scandal, with the intention of remaining in place until a successor is found. Two days later
Steve Barclay was announced as the new chief of staff alongside
Guto Harri as the new director of communications, replacing Jack Doyle. For his services, Rosenfield was nominated by Johnson for a
life peerage in the
2022 Prime Minister's Resignation Honours, and was created
Baron Rosenfield, of Muswell Hill in the London Borough of Haringey, on 13 July 2023. He sits as a
non-affiliated member of the
House of Lords, a choice which was criticised by some Conservative MPs.
Other roles Prior to taking up his Downing Street appointment, Rosenfield had been Chair of Trustees of
World Jewish Relief from October 2016, having served as a trustee since 2013. Rosenfield stepped down as Chair in January 2021 and was succeeded by Maurice Helfgott. In 2022, Rosenfield took up a role at
Centrica, and became non-executive Chairman of Windmill Hill Asset Management. == Personal life ==
