A celebration of the UK's birds of prey and images to mark the 75th anniversary of the D-Day landings are among new stamps being issued in 2019.
The Royal Mail will also issue stamps to mark the bicentenaries of Queen Victoria and Prince Albert and a set to celebrate British engineering.
A set of 11 stamps will be published for the D-Day anniversary, featuring images from the day itself. The Allied forces' landing on the beaches of Normandy is seen as a key date in the story of the Second World War.
A range of birds of prey have been photographed for Royal Mail, including the red kite, golden eagle and kestrel, and they will be featured on stamps being issued in April.
Forests and Royal Navy ships will mark special stamps being issued later in the year.
