A special service of remembrance is being held in London today in memory of British and Commonwealth soldiers who were executed by firing squad for alleged cowadice or desertion during the First World War.

The service 1100G at the Cenotaph in Whitehall comes on the eightieth anniversary of the end of the war, and is part of a long-running campaign for the soldiers to be given a posthumous pardon.

Their families say it's now officially acknowledged that many of those executed were shell-shocked and traumatised by the conditions they had to endure.

The British government turned down their request for a pardon earlier this year.
