Sir Julian Errington Ridsdale CBE (8 June 1915 – 21 July 2004) was a British National Liberal and later Conservative politician and long-serving Member of Parliament (MP) for Harwich.

The son of a stockbroker and nephew both of former Conservative Prime Minister Stanley Baldwin and Liberal MP Sir Aurelian Ridsdale, he was educated at Tonbridge School and at the Royal Military College, Sandhurst.

[citation needed] At the 1951 snap general election, Ridsdale stood as the Conservative Party candidate in the London seat of Paddington North,[1] but lost to the sitting Labour MP William Field.

Returning to the backbenches, he continued to mark himself as traditional rightwing Conservative, opposing tax increases and supporting capital punishment.

Retaining his wartime interest in Japan, Ridsdale concentrated on improving Anglo-Japanese relations and developing trade links.
