Britain's Home Affairs Select Committee is investigating ways to force New Zealand former judge Dame Lowell Goddard to answer questions about her troubled time leading a child sex abuse inquiry should she ever return to the UK.
Dame Lowell spent 18 months at the head of the Independent Inquiry into Child Sexual Abuse before her abrupt resignation in August.
In a letter released overnight to chair of the committee, MP Yvette Cooper, Dame Lowell criticised the British government for not defending her against what she calls "malicious defamatory attacks in some UK media".
Mrs Cooper in turn called it disgraceful that Dame Lowell said she wouldn't talk to the committee.
