John Aislabie, English politician, Chancellor of the Exchequer (born 1670)

John Aislabie, of Studley Royal, near Ripon, Yorkshire, was a British politician who sat in the English and British House of Commons from 1695 to 1721. He was of an independent mind, and did not stick regularly to the main parties. He was Chancellor of the Exchequer at the time of the South Sea Bubble and his involvement with the Company led to his resignation and disgrace.

The chancellor of the exchequer, often abbreviated to chancellor, is a senior minister of the Crown within the Government of the United Kingdom, and the head of His Majesty's Treasury. As one of the four Great Offices of State, the chancellor is a high-ranking member of the British Cabinet.
