Helen Cook will move across from her role at the Home Office, which she has held for a year-and-a-half, later this month.
Cook will report to the chief press officer Peter Graham, and takes her place as the final link in Clegg’s comms armoury.
Sorene told PRWeek: ‘The appointment is the end of a process that started last year with the restructure of Cabinet Office and Number 10 comms. I started as head of comms for the Deputy PM in January and we have reallocated resources within Cabinet Office comms.’
Cook formerly worked in the press office at the Department of Health and Downing Street, and has worked as a parliamentary assistant to Alan Milburn, the former Labour health secretary.
Cook joins Graham and senior press officers Robert Honey and Katherine Pateman.
Also working for Clegg is a small events and visits team led by Kate Whitty-Johnson with three visits officers.
Sorene pointed out that the team has been appointed within existing budgets.
Sorene was formerly head of news at the Department of Health and now works alongside Clegg’s political spokesman James McGrory and deputy director of comms Lena Pietsch.
Clegg’s press office’s remit is to support the Deputy Prime Minister and to deal with issues around constitutional and political reform.
In January, PRWeek revealed Downing Street was setting out plans to restructure comms and develop a team to work for the Deputy Prime Minister.
