On 5 May 2016, a spokesperson for Burnham confirmed that he had been approached by party officials in Greater Manchester, asking him to consider resigning from the Shadow Cabinet of Jeremy Corbyn in order to run in the upcoming mayoral election in 2017. On 18 May 2016, he confirmed that he was running for Mayor. Burnham was selected as the Labour candidate in August 2016. In September 2016, Burnham said that he would resign as Shadow Home Secretary once a replacement had been found, in order to concentrate on his mayoral bid. He was succeeded by Diane Abbott in October. Burnham said, if elected as Greater Manchester's mayor, he would resign his seat as the member of parliament for Leigh. However, the 2017 general election was declared a fortnight before the mayoral election; Burnham did not stand as a candidate.
