A British man has appeared in court after being charged by police in Ireland as part of an investigation into a death threat made to an MP.

Daniel Weavers, 41, who is originally from England but now lives in Douglas, a Cork suburb, was arrested on Saturday, as part of a gardai-executed search warrant at a residential property.

He has been charged with making a menacing message via phone on 18 October. The offence runs contrary to section 13 of Ireland's Post Office Act 1951, as amended in 2007.

Weavers made no reply in court on Sunday when the charge was put to him by the gardai (Irish police) in custody, and was granted conditional bail.

Conditions include abstaining from drugs and alcohol, surrender of his passport, making no unwarranted communication with the police, being able to be contacted on his Irish mobile phone, and checking twice a week at a police station in Cork.

It is believed that the death threat was made to a serving politician in Westminster, with The Irish Times reporting they are a female Labour MP.

The case will be held on 12 January, where instructions from the Director Of Public Prosecutions will be given.

It comes after the murder of Conservative MP Sir David Amess, who was fatally stabbed during a constituency surgery in Essex last month.

Ali Harbi Ali, 25, remains in custody charged with the politicians murder, and will enter a plea next month.

Sir David's death prompted conversations about the safety of politicians, with the Home Office announcing that MPs would be offered security guards while they hold their weekly constituency events.
