The royal was spotted in a smart all-purple ensemble as she arrived at the ceremony alongside her mother the Queen, ready to celebrate the Royal British Legion's landmark milestone. The 71-year-old royal opted for a beautiful wool coat with contrasting lapel detailing, worn layered over a simple dress. Anne completed the look with a fabulous hat boasting ribbon and feather embellishment in the exact same vibrant shade as her jacket's collar.

The Queen and the Princess Royal are leading the nation in marking the 100th anniversary of the organisation, which supports the nation's armed forces, veterans and the wider military family.

The legion is famed for its annual poppy appeal, which encourages public donations in return for the red flower pin to commemorate the UK's war dead.

Princess Anne will give a scripture reading on the theme of service, and there will be a rededication from the RBL's national president, reaffirming the legion's commitment to its work.
