Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many individuals from the Household Cavalry Regiment have been diagnosed as with noise and vibration sickness following operating in an Ajax-family vehicle a) before and b) after 23 July 2025.

The safety of our personnel is of paramount importance. I updated the House on 22 January 2026 on those injured as a result of the two incidents since November 2025, which includes Exercise Titan Storm.

However, we do not routinely provide medical information down to unit level as this would risk identifying individual personnel.
