The mother of a baby whose identity was stolen by a man jailed for 21 months has called for him to remain behind bars until he reveals his true name.
Christopher Buckingham married and has two teenage children
Audrey Wing, 66, from Edinburgh, said the case surrounding Christopher Edward Buckingham had caused her immense pain.
"He's been using the name for 23 years and they don't know who he is and he'll carry on with my son's name," she said.
Buckingham was sentenced at Canterbury Crown Court, Kent, on Tuesday but still refused to reveal his true identity.
Mrs Wing attended the court in October when he pleaded guilty to assuming a false identity.
"I couldn't take my eyes off him, trying to work out if I knew him. I'm still trying to work out whether I know him."
"I would like an apology and would like to know why he chose my son's name," she said.
Baby Christopher Buckingham died at the age of nine months
Buckingham's former wife and two children also do not know his true identity.
He married Jody in 1984, but they separated in 1996 and divorced in 1997. They have two children aged 19 and 17.
She said they had all moved on from their life with him, but the experience had left her feeling angry, while the children really did not know who their father was.
"In partnership with that they don't really have a past themselves on that side of their lives, and I think they'd like to know."
Jody said of her former husband: "It's far easier to carry on with a lie than it is to actually own up to the truth."
She fears her children will be unable to holiday abroad or visit relatives in Canada - their mother's country of origin - because of their father's refusal to reveal his identity and citizenship.
A UK Passport Service spokesman said: "We will be reviewing the issue of the passports as there may be issues of nationality and identity.
"We don't know anything about the father and there's nothing to say that he is British.
"We will have to review the state of those applications. There are very strict rules on entitlement to a British passport, one being the need to be a British citizen.
The children can hold onto their travel documents while the review is taking place, the spokesman said.
Police are passing Buckingham's fingerprints and DNA information to Interpol to send on to other countries.
Fraudulent information given by him includes that he was born in Lambeth, south London, and that both his parents died in an air crash.
Claims that his mother was born in 1952 also proved incorrect.
