The scientist at the centre of the row over the British government's Iraq dossier said his life had been made "intolerable", his family has revealed.
Dr David Kelly's wife Janice and daughters Sian, 32, and twins Rachel and Ellen, 30, issued a statement through Thames Valley Police after it was revealed the defence official died after slashing one of his wrists.
The statement, read at Wantage police station in Oxfordshire by Acting Superintendent David Purnell, also said the family was "utterly devastated" by the loss and paid tribute to Dr Kelly's "integrity, honour and dedication".
The statement added: "We are utterly devastated and heartbroken by the death of our husband, father and brother. We loved him very much and will miss his warmth, humour and humanity.
"Those who knew him will remember him for his devotion to his home, family and the community and countryside in which he lived. A loving, private and dignified man has been taken from us all.
"David's professional life was characterised by his integrity, honour and dedication to finding the truth, often in the most difficult of circumstances.
"His expertise was unique and universally respected and his life and achievements will always be a source of great pride to us.
"Events over recent weeks made David's life intolerable and all of those involved should reflect long and hard on this fact.
"We have been deeply moved by the many expressions of support from friends, family and the local community. We would also like to pay tribute to the professionalism and compassion of the officers of the Thames Valley Police force. It is hard to comprehend the enormity of this tragedy.
"We appeal now to everyone to afford us the privacy to grieve in peace and to come to terms with our loss."
