In 2011, the Arctic Monkeys hosted a two-day comeback festival at the adjacent Don Valley grass bowl to celebrate the release of Suck It and See. The band headlined and were supported on both days, by Miles Kane, The Vaccines, Dead Sons and Anna Calvi as well as local artists. Closure Reports emerged in January 2013 that Labour Sheffield City Council were considering demolishing the stadium as part of a money-saving exercise. It was suggested that regional athletics competitions would move to the city's smaller Woodbourn Road Athletics Stadium, which closed in 2011. The nearest major athletics stadium would then be the South Leeds Stadium in Leeds. The council confirmed the closure of Don Valley Stadium on 11 January 2013. A final closure date of 30 September 2013 was set by Sheffield City Council in April of the same year and despite a petition signed by 5,922 people campaigning against the closure, plans were announced by Labour Party Councillor Isobel Bowler to start the demolition of the stadium on 21 November 2013. Demolition contractor Demex began the demolition on this date, estimating that the process would take approximately six months. The Liberal Democrat Party leader and Deputy Prime Minister Nick Clegg opposed the stadium's closure, claiming the city council aimed to prevent the Save Don Valley Stadium group from obtaining central government grants in order to develop a business plan that would keep the venue open. The UK Independence Party also expressed opposition to the stadium's closure and stated their intention to put together a campaign to save the stadium. UKIP general secretary and Sheffield Branch chairman Jonathan Arnott commented that "there are so many examples of Council waste where cuts could and should be made without affecting local residents."
