The agency refused to confirm that it is working on crisis comms for Batmanghelidjh.
However it is understood that the agency has been counselling Batmanghelidjh on her personal media strategy for the past ten days.
A source said: "She has been under attack in the media for weeks now and has been hit by a deluge of bad and inaccurate press. She has been personally hurt by this and she needs help to put her case and make sure she is getting a fair share of voice."
Hillgrove6, run by its colourful chairman Richard Hillgrove, is known to favour a hardball approach to celebrity crisis comms. The agency represented Charles Saatchi during his divorce from Nigella Lawson two years ago. During the acrimonious hearings, 6 Hillgrove sent a series of strident releases to the national press detailing Lawson’s alleged use of cannabis and cocaine.
Kids Company closed suddenly on 5 August, less than a week after it received a £3m grant from the Cabinet Office authorised by ministers Oliver Letwin and Matthew Hancock, against the advice of senior civil servants.
On 2 September, Batmanghelidjh contacted PRWeek to clarify her relationship with 6 Hillgrove. "I wanted to make it clear that I have not hired such services and there is no formal arrangements for me to receive PR advice," she said in an email. "An individual attached to 6 Hillgrove was put in touch with me by a colleague and they very kindly wanted to see if they could be of assistance. Throughout this period, a range of people have offered their support, for which I am very grateful." PRWeek has amended the headline on this story to reflect this.
