At least 25 undercover police officers have spied and dated members of the public for a maximum of six years, making the life of women 'absolutely ruined', will reveal a new documentary.
Four of the spies would have caused children with their goals before they disappear while their descendants were still infants.
Some undercover officers were married and had their own children at the time of their alleged activities.
Although the scandal of 'Spionages', in which undercover officers were sent to spy on, mainly left-leaning activist groups between 1970 and 2010, has been known for several years now, there is a new documentary to reveal the scale of the deception.
One of those in the new ITV series, known as Jacqui, has told how she was 'absolutely ruined' after she happened to discover that her son's father had been an undercover officer about 20 years later.
Officer Bob Lambert is accused of leaving the couple when his son was still a baby and falsely claimed that he had to go abroad to escape from arrest.
More than 50 women have so far been confirmed as victims of the undercover officers, the Guardian reports.
From Thursday, the series – made in collaboration with The Guardian – will show how five women have combined the instructions to expose the real identity of their former partners.

Mark Kennedy would have relationships with at least 11 women he spied during the undercover in Bristol
The unity behind the practice, the NPIOU, operated in secret for decades that more than 1,000 political groups and even the Van Stephen Lawrence family, which was murdered in 1993.
A long -term public investigation into practice was set up by former Prime Minister Theresa May in 2015.
Under the leadership of retired judge John Mitting, the investigation into how women were cheated on women and who exactly knew about the sustainable of the undercover officers.
Last year it heard from his most important lawyer David Barr that sexual deception was 'not justified'.
It is assumed that a total of 139 officers in the service of two separate squadrons are involved in espionage activities.
This has been confirmed that 25 sexual relationships have entered into with goals – of whom there were only two women. Three further officers deny that they had sexual relationships with members of the groups they focused on.
The officers spent an average of four years as undercovers of the political groups, while reclaiming extensive information about protests, identities of members and even sexuities.
The e -mail previously reported on the case of undercover officer Mark Kennedy, who had sexual relationships with at least 11 women on which he focused.

Kennedy was part of the National Public Order Intelligence Unit (NPIOU) of the MET, which was employed together with the SDS Undercover officers

Eleanor Fairbraida is one of the 11 famous victims of Mark Kennedy – she entered into a sexual relationship with him and did not know he was sent to spy on her
Victim Eleanor Fairbraid became friends with Kennedy after he had joined the Sumac Center since 2003, a community hub in Nottingham.
It is known that he had sexual relationships with Fairbraida and no fewer than 10 other women during his efforts between 2003 and 2010 – in one of the largest police scandals in modern times.
Fairbraida, 46, who now lives in Bristol, said that she and Kennedy were seven years old friends after a meeting in the center and at one point their relationship progressed to become loved ones.
But all the time he was sent to spy on the work that the activists did and secretly married to two children.
Kennedy, 55, had a passport in his undercover name and attended meetings at power stations such as Drax in North Yorkshire and the G8 top in Gleneaagles in 2005, even traveling through Europe to 'participate in' protests.
He was so convincing in his role as an environmental activist who fights against climate change that he was even willing to be beaten up by the police while attending the protests.
Fairbraida continued: 'He moved to our house. I lived with him and three other people and then I stayed with him in his house.
“We were very good friends. I knew him for seven years. In 2008 our relationship developed and we were loved ones for a while.
“At that moment we had no idea that things like this happened.”

Kate Wilson, an environmental activist, was also duped in a long -term relationship with Undercover officer (shown together)

The special demonstration team was operational between 1968 and 2008, while the National Public Order Intelligence Unit worked between 1999 and 2010
Fairbraida said that Kennedy was also a long-term relationship with her friend Kate Wilson, when he pretended they supported the same football team, liked the same music and had the same 'trailer' lifestyle.
In 2021, Wilson won a milestone tribunal case against the metropolitan police for breaches of her human rights.
The tribunal – in which Fairbraid was a witness – heard that he had 'published by the police, laptops, passport and bank cards', all in his false identity, and 'had a bus issued by the police and a flat paid by the police'.
It was also heard that he was told to develop personal relationships to collect preventive intelligence on activists in the center, with the help of 'an extensive support system for this long -term infiltration'.
The relationships of Kennedy are just an example of the type of activities that is being investigated by national research.
Methods used by the police spies include the use of the names of dead children as coverage of identities without the permission of their families.
The families of 20 children born between 1938 and 1975 told that the details of their family members were used, 19 of whom had died young and the other where an officer used the identity of a living child.
