Operational Picture

📍
Location Strong
Trafalgar Square is consistently and directly identified across museum, parliamentary and image-caption sources.
👮
Police Presence Heavy
Hansard records that 522 officers of all ranks were engaged at the Union Movement meeting on 22 July 1962.
⚠️
Injuries Verified, Not Counted
Sources support that many people were injured, but the reviewed material does not provide one clean verified total.
🏛️
Policy Consequences
The incident fed directly into later parliamentary arguments over whether future Mosley or similar meetings should be permitted in the square.
⚠️ Reporting Caution The fact of the disorder, arrests and injuries is well supported. The weaker bits are the exact injury total and the disputed detail about whether Mosley fully reached the rally point.

Conflicting Information

The source set is strong on the riot itself, but not perfectly aligned on Mosley’s physical progress to the meeting and the exact size of the crowd.

Disputed Detail
Whether Mosley Reached the Rally Site

This is the clearest source clash in the file.

London Museum

States that Mosley and his son Max were escorted to safety by police, which places him at the scene.

Alamy Caption Snippet

Says Mosley was stopped before he set off from his flat.

The London Museum source is stronger here because it is tied to a specific object record of Mosley at the event.

Disputed Detail
Crowd Size

Sources broadly agree the crowd was very large, but not on one final exact number.

London Museum / Getty

Give the figure as 6,000 or over 6,000 people gathered to protest.

Later Secondary Quotation

A later blog citing the Birmingham Daily Post says the crowd was 7,000.

The directly reviewed source base supports 6,000 / over 6,000 more strongly than 7,000.

Unverified Details

These points were not firmly established in the supplied research.

Injury Total
Exact number of people injured.
Fatality Total
