A terrorist convict who launched an attack 10 days after his release from prison had boasted in jail of his intention to join ISIS and kill the Queen, an inquest has heard.

Sudesh Amman, 20, from Queensbury, North London, was under surveillance when he grabbed a 20cm carving knife from a shop and stabbed two passers-by in Streatham High Road in February last year.
