Григорий XII
Merke supported Richard against the usurper Henry IV and in 1400 was imprisoned in the Tower of London and deprived of his bishopric as a result. Although released and conditionally pardoned the following year, he was not restored to the bishopric, instead serving as a deputy and acting bishop in the Diocese of Winchester several times. He was one of those churchmen who sided against Pope Gregory XII at Lucca in 1408. He died in 1409.
