PRESS ASSOCIATION -- Military veterans and their families are due to gather for a service to mark the 90th anniversary of the Royal British Legion.
At Westminster Abbey, the charity will celebrate nine decades of supporting serving and ex-sailors, soldiers and airmen.
The Princess Royal, president of the Legion's Women's Section, will be part of the congregation and will later unveil a portrait of the Queen commissioned by the Legion to commemorate its milestone.
Artist Darren Baker, who produces highly realistic work, has painted the image of the monarch, patron of the Legion.
The charity was founded on May 15 1921 and brought together four national ex-servicemen organisations established to care for military personnel and their families after the First World War.
The physical injuries of the returning servicemen were not the only issues that needed addressing. Some men found it difficult to find work, which left their dependants in need.
During the following decades the charity has helped members of the Armed Forces from every major conflict.
The Legion is also famous for its poppy appeal, which encourages public donations in return for the red flower worn in memory of the UK's war dead.
