Usman Khan, a 28-year-old man with a terrorism conviction, was named as the suspect who was gunned down by police after the London Bridge stabbing terror attack.
Khan, 28, who stabbed two people to death on London Bridge on Friday, wrote in the letter published by ITV News he wanted to prove he did not carry extreme views following his terrorism conviction seven years ago.
Khan's lawyer Vajahat Sharif said there was no support available for him when he had asked to be put on a deradicalisation course.

Mr Sharif told The Guardian: "Maybe he was not ideologically robust enough to resist the radicalising groomers – I thought he was a reformed character."
