UK MPs have overwhelmingly voted in house of commons by 397 to 223 to authorise UK air strikes against so-called Islamic State in Syria.
During a 10-hour debate, David Cameron argued that action against the “medieval monsters” of IS was legal and would “keep our country safe”.
Labour leader Jeremy Corbyn said the case for war “does not stack up” – but his party was split, with senior Labour figures voting with the government.
The government has said bombing raids would begin “as soon as practical”.

Foreign Secretary Philip Hammond said he would not give a “running commentary” on operations, having earlier suggested bombings could begin as early as Thursday.
Welcoming the result, Mr Hammond said Britain was “safer because of the actions taken by MPs today”.
