AN MP is determined not to be "intimidated" by a Christmas death threat she has received.

Ynys Môn MP Virginia Crosbie was sent a handwritten note saying ‘traitors hang’ with an image of a noose. It turned up at the MP’s Holyhead constituency office on December 23 [it was opened by a staff member].

Both police and parliamentary liaison officers were "immediately" informed and North Wales Police have taken the note and launched an investigation.

“I will not be stopped from doing the job I was elected to do by the people of Anglesey and the coward or cowards who sent this note will not undermine democracy,” said Ms Crosbie.

“Too many times this sort of behaviour is tolerated but not by me. I will call out and relentlessly use all the avenues available to pursue all those who threaten myself, my family and my staff.

“The police have launched a wide-ranging investigation to find the people behind this threat and I thank them for taking it so seriously. They have several lines of investigation and I am awaiting an update from them.

“This corrosive behaviour is harming democracy and stopping people, especially women, from standing for public office. It has no place in our society and my approach remains one of zero tolerance.

"It's absolutely vital in a democratic society that we have disagreements and debate, not death threats.

“I would like to praise my staff for all the work they do, including having to see this sort of cowardly communication when they are opening the post. They shouldn’t have to.”

Ms Crosbie also released a copy of the note and asked people to call the police if they recognise the handwriting.

“This is a crime and if anyone thinks they know who wrote this note then I urge them to contact the police immediately,” she added.

A spokesperson from North Wales Police said: "I can confirm that we have received a report from the MP’s office, and the matter is currently being investigated."
