In April 2010, Fathers4Justice members backed Caroline Nokes as her party had supported its campaign for change to family law, promising legislation if they won the 2010 General election. However, although after the election, the Conservatives formed a coalition with the Liberal Democrats, the parties Coalition Agreement included aspects of the Fathers4Justice agenda. In accordance with this arrangement, the Government initiated a number of reviews, including the Family Justice Review (The Norgrove Report) and the Co-operative Parenting Consultation. After the consultations, the Government brought forward the Children & Families Bill. Whilst legal experts agreed these proposals were a considerable improvement on the previous situation it did not fully reflect the position of Fathers4Justice, and the group criticised the Coalition. In March 2013, Nokes announced she would sit on the committee responsible for scrutinising the Bill, Fathers4Justice called upon her to resign and organised a demonstration in Nokes' constituency.
Caroline Nokes stated that Fathers4Justice were encouraging their members to visit Nokes' family home at night, post late-night Tweets saying they were driving around her village 'looking for' her, asking members to send the MP their dirty underwear, demanding to see a Court Order outlining her daughter's living and contact arrangements, and falsely alleged her ex-husband was having difficulty having contact with his daughter. Fathers4Justice denies these allegations
Nokes commented in her local newspaper;
"I have been accused of...being an obstructive mother who denies her ex-husband access to our child. This is a completely baseless fabrication which nevertheless they repeat ad nauseam
. I have even had to involve the police over concerns for my daughter's safety. If F4J really want to deliver for their members, bullying, vandalising portraits of HM the Queen and harassing my constituents will not deliver it. They should have engaged with the legislative process when they were asked, and are now in danger of losing what little credibility they have left as a campaign group. The only people betrayed are F4J members who have been let down by the O'Connors."
Following a barrage of abusive tweets directed at Nokes, Twitter shut down the accounts of Fathers4Justice and Matt O'Conner, which F4J referred to as "political censorship" The local media reported the group had been engaged in a 'witch hunt' against Nokes, who pointed out she had "repeatedly offered to help Fathers 4 Justice with the tabling of amendments for the Children and Families Bill, but none were forthcoming, just comments, which Twitter agreed constituted abuse and harassment. I am aware other political parties and individuals have also complained to Twitter and indeed to the police". She also stated "I remain committed to improvements to the family justice system, which the Children and Families Bill goes some way towards delivering, and it is a pity F4J chose not to engage constructively with the deliberations of the Bill Committee.".
In February 2014, Nokes criticised a House of Lords' amendment to the Children & Families Bill which she said "watered down" the commitment to shared parenting, and spoke against the amendment in the House of Commons, arguing strongly in favour of shared parenting, saying shared parenting arrangements were in the best interests of children.
In October 2014, The Independent newspaper reported allegations the group may have put a tracking device on Nokes' car, and a security consultant claimed he had been approached by Nadine O'Connor about placing the MP under surveillance. Police were said to regard the group as a "fixated threat" which led to security enhancements at Nokes' home. When O'Connor confronted the Hampshire Police & Crime Commissioner making allegations about Nokes, the Commissioner stated O'Connor had "made things up". A person claiming to be a supporter of the group later sent Nokes a Facebook message which stated the wish that Nokes be "violently raped", and stated "there are a lot of people who wish you serious harm, torture and death. Watch your back".
Another national newspaper later published an article in which Nokes said the harassment was causing her to consider leaving Parliament on a weekly basis due to the impact it was having on her and her daughter. In return, the O'Connors claimed Nokes was waging a campaign of harassment against them, and took her and a friend whom they also claimed was harassing them to court to seek an injunction. However, at court the judge refused to grant the injunction because of "a total absence of evidence", with the judge criticising the O'Connors for seeking to prejudice the court by making "generalised assertions" and concluding "there's no sufficient evidence before me to support a finding that there's even an arguable case for a claim for harassment." The O'Connors were ordered to pay costs.
Nokes is divorced, and lives with her daughter.
