Jane Groom - acting director of comms at the Department for Communities and Local Government (DCLG) - is leaving the civil service after 15 years. She joins the LCA as a director at the end of November, reporting to MD Robert Gordon Clark.
She spent three years at DCLG, effectively the former Office of the Deputy Prime Minister.
Meanwhile, Rebecca Drake, head of comms at the London Resilience Team, is also joining LCA. Drake will take on the role of account executive in October. She was previously a senior press officer at the Charity Commission.
The London Resilience Team - comprising civil servants and representatives from the emergency services - is already on the hunt for Drake's replacement.
Groom told PRWeek: ‘I have always been involved in London issues and, after a long career in government, have been looking for some time to use my skills in a different environment.'
She is a previous head of media at the then Department for Environment, Transport and the Regions (DETR), which she joined in 1990 after a stint at the Department of Health.
At the DETR she worked closely with then minister for London John Gummer, and met LCA director Luke Blair, then a reporter on the Evening Standard.
LCA, based in Paddington, now employs 15 staff and holds accounts including British Waterways and Transport for London.
