Under-fire MP Lucy Allan today appeared to hit back at staffers who have accused her of “vicious” bullying, suggesting the claims were down to “personal disappointments”.

A long rebuttal was uploaded to the MP’s website this morning saying any bullying allegations against her were “unfounded”.

But the post, apparently penned by the MP herself, was then removed within hours.

Last week the Standard exposed calls made by Ms Allan to a member of staff in which the Telford MP describes her young staffer's sick leave as "pathetic".

In recordings heard by the Standard the MP tells Arianne Plumbly, 26, she has “pissed all over my life” and accuses her of having an “alcohol problem”.

Another former staffer, Katie Woodland, 32, told how the MP could “barrage you with viciousness”. Both spoke out despite allegedly receiving calls warning them not to.

In the post uploaded on to Ms Allan’s website today the author denied their allegations and repeated claims that Ms Plumbly was dismissed due to her “conduct, performance and absenteeism”.

The post adds: “Whilst it was certainly human to be frustrated and exasperated by Arianne’s conduct, it was wrong to express that frustration as I did, and I have apologised for this.”

Ms Plumbly denies having done anything wrong and told the Standard today that she has received no apology.

The author of today’s post on Allan’s website said they did “not know why” Ms Plumbly tried to contact Tory officials to complain about alleged bullying because “I was Arianne’s employer, not the Conservative Party.”

The post also pointed out that both Ms Plumbly and Ms Woodland failed to win seats in local government elections.

It then said: “Although I understand their personal disappointments, I do not believe either to be spiteful or malicious; I wish them both well for the future.”

Other former staffers have also come forward and spoken about the MP’s behaviour, with one saying of Allan “this was a person who bullies people”.

Today’s post is not the first instance of unexpected behaviour on the MP’s online platforms. Allan previously tweeted that she had received online abuse including a death threat. She posted an image of an email “from Rusty from Dawley” that ended with the line, “in which case there is no hope. Unless you die”.

She later admitted having added the words “unless you die” herself, which she said she had taken from a different message sent to her by someone else, adding that she might have “created a misleading impression”.

She also posted a video of herself online attacking local political opponents for being behind “smears, fear, lies, threats, slurs and abuse” against her, only to later take it offline.

Both Ms Plumbly and Ms Woodland have said complaints they made to the Conservatives about Allan’s behaviour were not dealt with effectively.

CCHQ has said complaints were dealt with “appropriately and sympathetically”.

The party is currently in the midst of an investigation into separate bullying allegations.

The other, unconnected, case is that involving activist Elliott Johnson, 21, who committed suicide in September after claiming he was threatened by “Tatler Tory” Mark Clarke, who denies the allegations.

The Standard has approached Ms Allan for a response.
