A jihadist who plotted a knife and gun rampage at attractions including Madame Tussauds and the Pride event has been jailed for a minimum of 25 years.
Mohiussunnath Chowdhury, 29, revealed his plans to undercover officers and bragged about being cleared of a sword attack on police outside Buckingham Palace in December 2018.
He was arrested three days before last year's Pride event but a jury found him guilty of terror offences in February.
The trial heard how he prepared for an attack by practising stabbing and beheading techniques, as well as booking shooting range training and trying to get a real gun.
His plans were discovered after the four undercover officers, posing as extremists, befriended him.
