In 1855, Wiseman applied for a coadjutor bishop. George Errington, who was then Bishop of Plymouth and his friend since boyhood, was appointed Coadjutor Archbishop of Westminster and Titular Archbishop of Trapezus. Two years later, Manning was appointed Provost of Westminster. Wiseman's later years were darkened by Errington's hostility to Manning, and to himself insofar as he was supposed to be acting under Manning's influence. The story of the estrangement, which was largely a matter of temperament, is fully told in Ward's biography. In July 1860 Errington was deprived by the Pope of his coadjutorship with right of succession. He retired to Prior Park, near Bath, where he died in 1886.
