An alleged National Action member from Skelmersdale has pleaded guilty to plotting to kill West Lancashire MP Rosie Cooper.
Jack Renshaw, 23, has pleaded guilty at the Old Bailey to preparing acts of terrorism by plotting to murder MP Rosie Cooper with a Gladius knife last summer.
On the opening day of his trial, Renshaw pleaded guilty to preparing acts of terrorism as well as making a threat to kill police officer Victoria Henderson.
Judge Mr Justice Jay directed the jury to deliver a formal guilty verdict on the first two charges Renshaw faces.
He is on trial alongside Christopher Lythgoe, 32, from Warrington, who denies giving Renshaw permission to murder the West Lancashire MP on behalf of National Action on July 1 last year.
The pair, along with Garron Helm, 24, of Seaforth, Merseyside, Matthew Hankinson, 24, of Newton-le-Willows, Merseyside, Andrew Clarke, 33, and Michal Trubini, 35, both of Warrington, also deny membership of the banned far right group.
