A 21-year-old female student was on Tuesday found guilty of trying to murder Labour MP Stephen Timms in revenge for him voting for the 2003 invasion of Iraq.
Roshonara Choudhry stabbed the former Treasury minister twice in the stomach during a knife attack at his east London constituency office on May 14.
The assault was a "punishment" and "to get revenge for the people of Iraq", prosecutor William Boyce told the Old Bailey.
Choudhry refused to attend court. She told her barrister Jeremy Dein that she did not accept its jurisdiction and did not wish him to challenge the prosecution case.
She was convicted Tuesday after less than 15 minutes of deliberation. She is due to be sentenced Wednesday.
The decision to join US-led invasion was the most controversial episode of Labour's 13-year tenure, provoking huge protests, divisions within the party and accusations that then Prime Minister Tony Blair had deceived the public about the reasons for invasion.
