Today, we gathered in Bracknell for a service of thanksgiving for the life of Martin Dixon.

With much sadness, we announce the death of Martin Dixon on 15/10/2025, having had cancer for over 5 years. He was a long-time member, former chairman.
He & Linda enjoyed many happy times together, including organising numerous Sub Brit trips.
We'd love to hear your anecdotes & memories of Martin.
