A Tory MP who voted to bomb Syria was criticised today after she doctored an email from a constituent so it read like a death threat.

Lucy Allan, 51, published a genuine email from a voter who branded her 'an empty shell of a human being' and 'detached from reality' but added the words 'unless you die' and put it on Facebook.

Sender Adam Watling, 27, who was writing as Rusty Shackleford, claims she deliberately added the final three words to make it appear as though he had sent a death threat.

Mrs Allan has since deleted the Facebook post, claiming that the three extra words were from another email and the post was an 'illustration' of the unpleasant comments she had received.

Row: Tory MP Lucy Allan has deleted this Facebook post quoting an email from a constituent after being accused of adding the words 'unless you die'

Upset: Mrs Allan says she is the victim of abuse over Syria - but said it was two emails put into one - Adam Watling, right, says he has been smeared by having words he did not say added to his email

Afterwards: Mrs Allan then posted this comment admitted the words came from two different emails - but says she has been targeted by people using pseudonyms and has gone to the police

The Tory MP, who was elected in May, says she has gone to the police who are investigating harassment by Labour activists in her constituency.

Mr Watling, an audio producer from Telford who uses the pseudonym Rusty Shackleford, said: 'I think this is deceitful and it calls into question her integrity. The fact she is doing this and also representing voters is very worrying.

Claims: Mrs Allan says Scotland Yard is investigating correspondence sent to her from various people and alleged she is being harassed

'I would like her to resign as it is a serious thing for an MP to do to someone, to misrepresent an email from a constituent so grossly.

'Despite changing my Facebook name, I am a genuine Telford constituent and I have lived here all my life.

'And just because I emailed under a different name, why does that make it OK to add a death threat to my email?

'I would never say the words she attributed to my initial email. I do not understand why she would take the comments she may or may not have received from someone else and add them to my email when she put it on her Facebook.

'I just don't understand why that gives her the right to add three words to my email. This is not selective editing, this is adding things I did not say'.

It comes after several Labour MPs who backed military action in Syria received sinister messages on social media from aggrieved constituents.

Claims: Mr Watling, an audio producer from Telford who uses the pseudonym Rusty Shackleford, said: 'I think this is deceitful and it calls into question her integrity

Email: Adam Watling, who wrote the original email, admits he was rude but says it is clear that it ends with 'there is no hope' - not 'unless you die'

Mr Watling, who wrote under the pseudonym Rusty Shackleton, sent the email in question on November 27, after being inspired by a round-robin email telling people to get in touch with their MPs.

He used a ready-made template from anti-bombing campaigners asking her to vote against bombing Syria, before adding a 'cheeky' message at the end calling the MP a 'robot' and 'containing nothing but pure venom and spite for anyone worse off than you'.

Mrs Allan posted the latter part of the email out of context on her Facebook page later that day under the heading: 'This is from Rusty from Dawley' – and added the three words 'unless you die'.

But Mr Watling quickly commented on her post, pointing this out and stating that 'I would never wish death on anyone. Even a soulless Tory liar such as yourself'.

Minutes later the entire thread was deleted from the MP's Facebook page and second post was put up from Mrs Allan explaining that the 'Rustygate' comments were real but were from a different email. She will not say who from.

However after backlash from commenters on social media, this post was also shortly removed.

Mrs Allan said: 'Rusty Shackleford' is a pseudonym. It is the name of a cartoon character. There is no one by that name on the electoral roll in Telford.

'Using this pseudonym, I was sent an email which contained abusive comments. I wrote a post on my Facebook page about online abuse.

'I used the unpleasant comments that I had received as an illustration of this abuse. I later received more abusive comments and I added these to my post.'

She added: 'My Facebook is my Facebook and I can write on it what I want. What I did was selective editing and I am allowed to do this.'

Her spokesman added she claims have been to to the police over a campaign of abuse in her constituency.

She said: 'My records show that no one by the name of Mr Watling has contacted me. Nor have I, or my office, ever contacted anyone by the name of Mr Watling.

'On Wednesday I reported a crime to the Metropolitan Police and produced evidence. More evidence is coming to light and is being passed on to them.
