Coleen Rooney reveals how she went about Wagatha

Coleen Rooney has revealed more details of how she went about her so-called Wagatha Christie investigation in 2019.

She famously used social media to identify who was leaking private information about her to the press.

Rooney ultimately pointed the finger at Rebekah Vardy, who denied leaking the stories and sued Rooney for libel.

Rooney said she suspected Vardy due to her existing relationship with the Sun, and also knew her friends in Liverpool would not work with the newspaper.

Vardy, the wife of footballer Jamie, lost her legal case last year and was ordered to pay 90% of Rooney's legal costs, after a judge ruled Rooney's accusation was "substantially true".

Rooney told BBC Radio 4's Woman's Hour: "It all boiled down to, this is someone who has a connection with this newspaper, that [the stories] kept going to all the time."

She told presenter Emma Barnett that she noticed stories about Vardy had appeared regularly in the newspaper when she searched.

"I looked through the list [of Instagram followers] - obviously there was a connection when I Googled, there was a lot of Sun exclusives," Rooney said.

"But there were the WhatsApp messages from previous [chats with Vardy]. Rebekah reached out to me a lot, whereas I never reached out."

Rooney, the wife of footballer Wayne, appears in a new Disney+ documentary about the case.

Rooney continued: "We don't live near each other, we're only connected through our husbands playing for England together which is once in a blue moon. It's not like a week-in, week-out football club where they'd get to see each other.

"So it was from time to time, and I read over the messages back as far as it went, and it became relevant that it could be her account, because she wanted to keep in touch. The messages, I don't know you just get that feeling where things don't add up."

Rooney said Vardy also noticed when Rooney had blocked her on the platform, and messaged her to ask about it.

"I did block [Vardy] beforehand," Rooney said. "And then Rebekah reached out and messaged and said 'have you blocked me?'

"So I followed her back and said it must have been a mistake, and accepted her back into my account. And from there, I did more and more fake posts, which, some of them then did go on to be in the newspaper."

Rooney said another way she was able to narrow down the list of suspects was that she assumed none of her family or friends from Liverpool would work with the Sun.

The paper attributed the crush to the behaviour of Liverpool fans, but it had actually occurred due to weak stadium infrastructure, poor officiating by police and severe overcrowding.

Many newsagents in Liverpool refuse to stock the newspaper as a result. Rooney said she knew her friends and family would "definitely not" work with the Sun.

"It's something that Scousers wouldn't do," she said.

"So obviously that eliminated a lot of other people from my followers that I probably wouldn't have thought it was, but [because of] that fact it wouldn't have been."

Rooney's original sting involved posting fake information about herself on her private Instagram stories - she had both a public and private account - to see which ones would end up being reported in the press.

She then limited the number of people who could access her private Instagram stories, eventually leaving Vardy's account as the only viewer.

After the false stories appeared in the Sun, Rooney released a statement on social media explaining what she had done and accusing Vardy of being the leaker.

The affair was quickly nicknamed Wagatha Christie, a reference to Wags - a term used to describe the wives and girlfriends of footballers, and to the author Agatha Christie, famous for her detective novels.

Rooney told Radio 4 it was "really frustrating that someone was giving my private information to a national newspaper", adding: "It's private for a reason.

"Some of the stories, I wasn't bothered that they were out there, but it was the fact that it was wrong to leak someone's private information, that was my whole thought process behind it, it shouldn't be getting done."

She continued: "I deal with my personal life behind closed doors, which is completely different to how the court case played out. It was so public, because it was a legal matter."

Rooney described the court battle as "one of the toughest times I've had" in her life, adding that she did not expect it to end up in court.

"I would never in a million years have thought a court case could come from that," she said. "I did not want to go to court and I was terrified because I've never been in a court room before, never been through that type of legal battle."
