King Charles will feature on UK stamps for the first time today as the new design is launched.
The King's image, an adaptation of artist Martin Jennings' design for use on coins, will appear on the new stamps from Tuesday, April 4.
Despite the launch, stamps will not be available for purchase in post offices or other retailers until those featuring an image of the late Queen are used up. King Charles requested that stamps featuring his mother are used up rather than destroyed, according to Royal Mail director of external affairs and policy David Gold.
