Christian Horner's accuser has reportedly hired a David Cameron ally as she continues to fight Red Bull's decision to clear the 50-year-old of misconduct.
The F1 side cleared Horner of inappropriate behaviour last month, with the Briton always maintaining his innocence.
However, the female employee who made the allegations is still fighting to get the decision overturned.
The staff member, who hasn't been named, is currently suspended on full pay. Red Bull have not disclosed the reason for her suspension.

According to the Daily Mail, the worker is paying legal bills running into the hundreds and thousands of pay.
After opting to ditch UK law firm Lewis Silkin she is now working with Goodwin Procter, who are based in the United States.
And it's also claimed she has hired Giles Kenningham, who has previously served as head of press for David Cameron when he was Prime Minister.
Cameron awarded Kenningham an MBE in 2016 in his resignation honours upon leaving 10 Downing Street.
Since leaving that role he has set up his own PR Agency and also co-hosts his own podcast, the Hacks and Flaks podcast.
Horner has continued to work as normal despite the probe into his conduct.
He oversaw Sunday's Australian Grand Prix, with Red Bull enduring a difficult day as Carlos Sainz Jr secured victory.
Max Verstappen was forced out of the event after just three laps, with the 26-year-old visibly frustrated.
Sergio Perez could only finish fifth for Red Bull.
And Mercedes duo George Russell and Lewis Hamilton failed to finish the race as well, with Russell involved in a horror crash on the penultimate lap.
Horner has insisted he has no desire to leave Red Bull.
Those close to the 50-year-old say he is currently a pawn in a wider power struggle at the company.
Earlier this week rumours suggested Horner was looking to become CEO of the entire Red Bull operation.
However, they have since been debunked with Horner reportedly solely focused on racing matters.
Writing on social media after the race Down Under, meanwhile, Horner insisted Red Bull would look to improve in the next race in Japan on April 7.

"Not the race we were looking to run today, but the fact that it’s Max’s first DNF since 2022 - coincidentally also here in Melbourne - is a marker of the incredible run we have been on as a team," he said.
"@SChecoPerez at least did well to bring home some points and P5 after picking up some floor damage.
"We were hard on the tyre, which is very unusual for us, but will look to resolve in time for Suzuka.
"For Max, it felt like the brakes were locked from the start of the Grand Prix, so effectively he was driving with the handbrake on and ultimately ended with the rear right overheating and failing dramatically to bring an early finish to his race."

Verstappen, despite his issues at Albert Park, will be the favourite for the Japanese Grand Prix.
He's won the race in each of the past two years and, given his form over the past couple of years, a hat-trick of triumphs is certainly a possibility.
