UK veterans of the landing in World War Two, who arrived in France 70 years ago, will be on HMS Bulwark as it sails to Normandy from Portsmouth.
Former troops, cadets and serving members of the armed forces will parade in Portsmouth.
In France, the Prince of Wales is to attend a memorial service to mark the taking of the strategic Pegasus Bridge, captured by British troops minutes after landing.
The Queen and Duke of Edinburgh will mark the D-Day anniversary during a state visit to France which begins later today in Paris. They'll attend an international service of commemoration attended by royals, presidents and prime ministers.
