History of the Green Party of England and Wales of Deputy Leader. The Green Party fielded more than 300 candidates for the 2010 general election. Caroline Lucas became the first Green candidate to gain a seat in Westminster, after being elected MP for Brighton Pavilion by a margin of 1,252 votes. The following week 600 new members had joined the Green Party bringing total membership to over 11,000. In previous years 600 new members was high for a whole year. On 24 May 2012, the six Green Party councillors elected to Stroud District Council formed a power sharing administration (a "constructive cooperation") with both the Labour Party and the
2015 United Kingdom general election in England leading to the resignation of its leader Nigel Farage. The Green party increased its share of the vote and held Brighton Pavilion but also failed to make any gains. The recorded swing in each case is calculated as two-way swing from the party that won in 2010 to the party targeting the seat. Negative swing implies that the targeting party lost votes to the incumbent party. Swing for the Greens is measured as one-party swing, i.e. the change in the party's share of the vote. 2015 United Kingdom general election in England The 2015 United Kingdom general election in England
