He was furthermore appointed to a variety of committees concerning French aggression against the Dutch and with the spreading rumours of the 'Popish Plot' which caused a renewed anti-Catholic hysteria in England and Scotland, Cavendish was tasked with the protection of the King and an investigation into the murder of Sir Edmund Berry Godfrey. These tasks included and incurred a number of anti-Catholic measures, e.g. considering to remove all Catholics from London and to exclude them from parliament via law. Generally, Cavendish's are not as staunchly whig as has been judged previous and in his later political career, he did not fulfil any substantial leadership roles as would have maybe been expected. His overall legacy, however, includes the transformation of Chatsworth house and the supply of works of art for the architectural feat. Ejected for non-payment of arrears 22 July 1685.
