 Once the three dioceses were dissolved by the scheme on 20 April 2014, the diocesan see of Leeds was newly constituted a diocesan see, whose incumbent, the Bishop of Leeds is bishop over the whole diocese generally and the Leeds episcopal area specifically.He has cathedrals at Ripon Cathedral, at Wakefield Cathedral, at Bradford Cathedral, and (if and only if he designates the minster as a pro-cathedral) at Leeds Minster.It was announced on 8 November 2013 that retired Bishop of Southwark Tom Butler would serve as "mentor bishop" for the diocese prior to the first diocesan bishop taking post.
