Sir Robert Salusbury Cotton, 5th Baronet

Sir Robert Salusbury Cotton, 5th Baronet (c. 1739 – 24 August 1809) was an English politician who sat in the House of Commons from 1780 to 1796.

Soon after the birth of his second son, he moved from Lleweni Hall to Combermere Abbey, the traditional seat of the heir apparent to the baronetcy.

[6] Cotton was returned unopposed as Member of Parliament (MP) for Cheshire at a by-election on 1 March 1780 and at the succeeding 1780 general election.

In 1784 he was a member of the St. Alban's Tavern group which aimed to reconcile Charles James Fox and William Pitt the Younger.

His brother later stated that this was due to ill health and that he had declined a peerage, but contemporary accounts claimed it was in annoyance at not being given the post.
