A critic of the UK's involvement in the wars in Iraq (2003–11) and Afghanistan (2001–16), Choudary praised those responsible for the 11 September 2001 and 7 July 2005 attacks. He promotes the implementation of Sharia law throughout the UK, Poland and India. He marched in protest at the "Jyllands-Posten" cartoons controversy, following which he was prosecuted for organising an unlawful demonstration. During a protest outside Westminster Cathedral in 2006, Choudary told demonstrators that the Pope should be executed for insulting Islam.
