Undercover police relationships 'outrageous'

Abuses connected with undercover police activities show that an urgent review is needed of laws covering such work in England and Wales, MPs have said.
The Commons Home Affairs Committee said the law failed to protect the rights of those affected, including those in relationships with undercover officers.
It said forces whose officers used dead children's identities must apologise.
Harriet Wistrich, a solicitor acting for eight women who have had relationships with undercover police, including three who gave evidence to the Home Affairs Committee, told Today presenter Justin Webb that "its' outrageous that this kind of infiltration should take place".
James Banham, a former undercover police officer, said that he could see circumstances where this sort of activity could be justified but insisted that this would be only in "extreme circumstances".
