In October 2001, Corbyn was elected to the steering committee of the Stop the War Coalition, which was formed to oppose the Afghanistan War which started later that year. He helped organise the February anti-Iraq War protest which was claimed to be the largest such protest in British political history. In 2006, Corbyn was one of 12 Labour MPs to support Plaid Cymru and the Scottish National Party's call for a parliamentary inquiry into the Iraq War. He was elected chair of the coalition in succession to Andrew Murray in September 2011, but resigned in September 2015.
