Portsmouth:A 37-year-old anti-migrant activist has pleaded guilty to slashing a migrant boat with a knife in the English Channel in September.

According to Anadolu Agency – English, Daniel Thomas, also known to his supporters as Danny Tommo, was arrested in September after a video surfaced showing him slashing a boat in the English Channel with a knife.

Thomas admitted to the charge at Portsmouth Crown Court but pleaded not guilty to a separate offense of failing to disclose his phone's PIN to police, as reported by Sky News. Reports also indicated that a French coastguard official was on board when Thomas appeared to slash the vessel.

After the incident, Thomas was heard saying, "This is what needs to happen to everyone in these boats," and continued, "Right, you're on English territory, this is England, this is not France anymore … get off the boat, you have time to get off the boat. This is not France. Take them back."

Judge James Newton-Price KC has set Thomas's sentencing for November 18 and has remanded him in custody.
