As Clement was at that time a prisoner of Charles V, the Holy Roman Emperor, as a result of the Sack of Rome in May 1527, Knight had some difficulty obtaining access. In the end he had to return with a conditional dispensation, which Wolsey insisted was technically insufficient. Henry then had no choice but to put his great matter into Wolsey's hands, who did all he could to secure a decision in Henry's favour, even going so far as to convene an ecclesiastical court in England, with a special emissary, Lorenzo Campeggio, from Clement to decide the matter. But Clement had not empowered his deputy to make a decision. He was still Charles V's hostage, and Charles V was loyal to his aunt Catherine. The Pope forbade Henry to contract a new marriage until a decision was reached in Rome, not in England. Convinced that Wolsey's loyalties lay with the Pope, not England, Anne, as well as Wolsey's many enemies, ensured his dismissal from public office in 1529. Cavendish, Wolsey's chamberlain, records that the servants who waited on the king and Anne at dinner in 1529 in Grafton heard her say that the dishonour Wolsey had brought upon the realm would have cost any other Englishman his head. Henry replied, "Why then I perceive...you are not the Cardinal's friend." Henry finally agreed to Wolsey's arrest on grounds of "praemunire". Had it not been for his death from illness in 1530, Wolsey might have been executed for treason. In 1531 (two years before Henry's marriage to Anne), Catherine was banished from court and her rooms given to Anne.
