The Mail is quite wrong in referring to FM Lord Bramall as a 'retired general'. At the age of 86 he continues to be a serving officer. Along with 74 year old FM Lord Inge.
Field marshals are unique in remaining on the active list for life. It's one of the delightful minor quirks that continues to elude Labour's ruthless destruction of all such national idiosyncrasies.
And Ld Bramall at 83 still had the sense to deck the repulsive Greville Janner in 2006.
