The 2015 Middlesbrough Borough Council election took place on 7 May 2015 to elect members of Middlesbrough Borough Council in England.[1] It took place on the same day as the election for the Mayor of Middlesbrough, as well as the UK general election, and other local elections across England.[2] Since the 2011 election, there had been boundary reviews, which resulted in two fewer seats on the council, many old wards being discontinued and new wards being formed.[3]
