The Marquis de La Fayette, apparently jealous of Philippe's popularity, persuaded the king to send the duke to Britain on a mission, where he remained in England from October 1789 to July 1790. On 7 July 1790, he took his seat in the National Constituent Assembly. On 2 October, both he and Honoré Mirabeau were declared by the Assembly entirely free of any involvement in the events of 5–6 October 1789.
