Sir David Anthony Crausby (born 17 June 1946) is a British Labour politician who served as Member of Parliament (MP) for Bolton North East from 1997 to 2019.

He represented the UK internationally as a delegate to the Nato and Council of Europe Parliamentary Assemblies, and was knighted in the 2017 New Year Honours.

He contested the Conservative-held marginal seat of Bolton North East at the 1992 general election where the sitting MP Peter Thurnham was defending an 813 majority.

He made his maiden speech on 17 July 1997, in which he remembered the inventor of the spinning mule Samuel Crompton who was born in Bolton.

He lobbied the last Labour government to address overcrowding and opposed the idea of a Greater Manchester congestion charge because of the lack of viable alternatives.

[11] In 2018 Crausby led a debate on Northern trains and called for the resignation of Transport Secretary Chris Grayling after the disastrous May timetable caused mass disruption across the North of England.

[17] Subsequently, in May 2013 the MP voted against the bill’s third and final reading,[18] opposing the legalisation of same-sex marriage within England and Wales.

His eldest son, also named David, is a commercial and editorial photographer; his work is represented by several agencies including Getty Images and Alamy.
