A British teenager accused of holding extremist beliefs pleaded guilty to planning an Islamist terrorist attack, allegedly with the intention to target police officers or military personnel.

Prosecutors said Matthew King, 19, carried out surveillance at police stations, railway stations, a magistrates court and a British Army barracks.

At a hearing at the Old Bailey in London on Friday, King pleaded guilty to preparation of terrorist acts.

The teenager stood in the dock to enter his plea wearing a grey shirt and sleeveless black padded jacket.

His lawyer, Hossein Zahir KC, said the defence had submitted a basis of plea to the court.

Judge Mark Lucraft KC adjourned sentencing until April 14 for a pre-sentence report to be prepared, which will include the issue of the danger posed by the defendant.

Addressing King, Judge Lucraft stressed it was in his "best interests" to help those preparing the report.

Speaking quietly in the dock, King replied: "Understood."

Authorities had been tipped off about King through an anti-terrorist hotline and the Prevent counter-terrorism programme after he posted a video on a WhatsApp group on April 13 last year.

In it was an image of a male holding a knife with the words: "Those who said that there is no jihad and no battle. They are lying!

"Our jihad will continue until disappearance, until the day of judgment! Now the battle has begun and it will continue until the day of judgment. So take out your sword, O youth, and destroy the kufr."

King, from Wickford, Essex, was arrested at his home on May 18 by officers from the Metropolitan Police Counter Terrorism Command and his mobile phone was examined.

After being cautioned, he responded: "I don't believe in the UK law, the only law I believe in is the law of Allah."

He was subsequently charged with preparing an act of terrorism between December 22, 2021 and May 17, 2022.

Prosecutors alleged the plot was related to extreme Islamist beliefs and that King carried out surveillance at railway stations, police stations, Stratford Magistrates Court in east London and an Army barracks in East Ham, also east London.

At an earlier hearing, prosecutor Gillian Curl had said that no "specific act of terrorism" had been identified.

But she said: "He was preparing for an act against either serving on-duty police officers or military personnel."

The defendant has been in custody since being charged.
