The king was due to open parliament, but owing to illness (a recurrence of porphyria, that had prompted the Regency Crisis in 1788 – see Godwin's entry for 20 November 1788) had been unable to do so. The House adjourned until 15 November, on which date, the king’s health not having improved they adjourned for a further fortnight, and thereafter for a further fortnight. Following this, a Regency Bill, conferring authority on the Prince of Wales was debated and passed, with a range of restrictions attached. The expectation was that the prince as Regent would dismiss the government of Perceval and call for a Whig government, but he disappointed Whig expectations, keeping the government.
