I think the working royal roster has already been reduced in recent years.
Working:
KC III
Camilla
Princess Anne
Prince of Wales
Princess of Wales
Edward and Sophie Wessex
Working but likely to retire soon with no replacement (all are past regular retirement age):
Duke of Kent (his wife the duchess retired years ago)
Duke of Gloucester
Duchess of Gloucester
Princess Alexandra
Gone:
Prince Michael of Kent - retired
Randy Andy
Halfwit
MeGain
