Belinda Harvey, who had relationship with Bob Lambert, says it is ‘beyond comprehension’ that she had been used

An undercover police officer who deceived at least four women into sexual relationships and fathered a child with one of them is a “cruel and manipulative” liar, a public inquiry has been told.

Belinda Harvey, one of the women who had an 18-month relationship with Bob Lambert without knowing his real identity, said it was “beyond comprehension” how the undercover officer had used her.
