Scotland Yard apologised to seven women who were deceived into "abusive, deceitful, manipulative and wrong" relationships with undercover police officers.
The Metropolitan Police said it has reached a settlement with the women over civil claims relating to the "totally unacceptable" behaviour of a number of officers working for two now disbanded units.
Assistant Commissioner Martin Hewit said: "I acknowledge that these relationships were a violation of the women's human rights, an abuse of police power and caused significant trauma.
"I unreservedly apologise on behalf of the Metropolitan Police Service. I am aware that money alone cannot compensate the loss of time, their hurt or the feelings of abuse caused by these relationships."
