The Parliamentary Secretary to the Board of Trade in the United Kingdom was a member of Parliament assigned to assist the Board of Trade and its President with administration and liaison with Parliament.
From September 1953, a more senior ministerial post, the Minister of State for Trade also existed.
At times, the Parliamentary Secretary post was then filled by a member of the House of Lords.
The role of Parliamentary Secretary to the Board of Trade therefore ceased to have practical application beyond that date.
The closest successor can be found in the role of Parliamentary Secretary to the Department of Trade and Industry.
