Camila Batmanghelidjh, the founder and former chief executive of the collapsed charity Kids Company, has secured a deal to write a book about the charity’s model of care.

Kids will be co-authored by Tim Rayment, a journalist on The Sunday Times, and released in October 2016, according to its publisher Biteback.

Biteback said in a statement that the book would reveal the true scale of Britain’s failure in children’s services, along with details of two decades of candid exchanges with prime ministers and senior politicians. The book will also discuss Kids Company’s breakthroughs in the care of young people.

Kids Company offered care and support to vulnerable children and young people in London and Bristol, but closed abruptly last summer amid allegations of financial mismanagement and inappropriate staff behaviour.

A report by the Public Administration and Constitutional Affairs Committee, published in February, found a "catalogue of errors" had led to the charity’s downfall. It said trustees ignored repeated warnings about the charity's financial health, and did not address increasing concerns about the suitability of its programmes and the behaviour of staff members, including Batmanghelidjh.

The report also criticised the charity for failing to hand over details of vulnerable clients to Southwark Council earlier in the year so their care could have been transferred before its closure.

Batmanghelidjh said in a statement: "Over two decades, thousands of staff, volunteers, clinicians, donors, children and families worked together to create a community in Kids Company that vulnerable children and young people could trust and be strengthened by.

"So much was learnt through trial and error, research and practice. In writing this book, we can share the learning.

"This is also a book about the truth that too many people were too scared to hear, and it is dedicated to all the children whose bravery inspired us every day to keep going against the odds."

Biteback said in the statement that Batmanghelidjh’s share of the proceeds would be donated to the Family Food Bank, an organisation set up to support the children and families affected by Kids Company's closure.

Rayment said: "People understand instinctively that the collapse of Kids Company obscures a bigger truth. This is an untold story from a silenced voice."
