Investigators are questioning the woman at the center of Christian Horner’s ‘sexting scandal’ this week as part of an appeal after her complaint against the Red Bull boss was rejected

Investigators are due to question the woman at the center of Christian Horner’s ‘sexting scandal’ this week as part of an appeal after her complaints against the Red Bull boss were dismissed.

The woman, who was suspended from her job at the company’s UK headquarters, contested the independent report that cleared Horner of any wrongdoing after she accused him of “coercive behaviour”.

A new lawyer has reportedly been appointed to grill her ahead of the appeal and is due to speak with her within days.

The re-inquest could also see Horner – who is married to former Spice Girl Geri Halliwell – questioned about the case again.

Allegations of ‘inappropriate behaviour’ by Horner were dropped just a day before the first practice session at the Bahrain Grand Prix.

But just 24 hours later, his alleged wrongdoing was thrown back into the spotlight after what appeared to be intimate WhatsApp exchanges allegedly sent by Horner to the female colleague were leaked to a number of key F1 figures and the media.

Bosses are unlikely to reveal the full investigation report into the scandal as both parties have signed non-disclosure clauses.

Ahead of the appeal, an F1 source told The Sun: ‘Nobody wants this to drag on any longer than it has to.

The woman, who has been suspended on full pay, also changed lawyers – a precursor to her latest legal action.

‘Red Bull have made it clear that once the appeal is over they are willing to be completely transparent.

“They don’t want to do anything that compromises the process, but when it’s done, the gloves are off.”

The woman has lodged a separate complaint against Horner with the FIA ​​- the sport’s governing body.

The female employee, it is believed, insists that she was not the source of the explosive evidence. And someone close to her says she feels ‘let down’ by Red Bull and has ‘behaved properly during the process.’

A friend of the woman exclusively told MailOnline: ‘She’s so disappointed with how it’s all gone, especially as she did everything by the book.

‘She raised her concerns privately and did everything right, but she feels very let down by the company.

‘They have suspended her as she followed due process diligently and correctly.’
