The 500 square metre flag was unfurled at the campaign launch

The 500 square metre flag, unfurled on Wednesday, carries the word "thanks".

The Royal British Legion staged the event as part of a campaign to give the public a chance to thank the men and women who fought in WWII.

Pte Johnson Beharry VC, the first living recipient of the Victoria Cross since 1965, was a guest at the launch.

He was recognised for his courage under fire while serving in Iraq.

On Wednesday, he said: "I am very proud to be here today to support The Royal British Legion's campaign.

"Having been in conflict myself, I know the sacrifices thousands of men and women made for our freedom.

"I am proud and delighted to take part in The Nation's Biggest Thank You."

'Gratitude and respect'

The launch party gathered on board the HMS Albion in Dover Harbour to watch the Victory flag cascade down the cliffs.

Brigadier Ian Townsend, Secretary General for The Royal British Legion, said: "This campaign is about acknowledging the heroism of every single man or woman who fought for our freedom in World War II.

"Whether in the jungle in Burma, on the beaches of Normandy, or in a munitions factory in Manchester, everyone was indispensable to the success of the war effort and deserves our wholehearted gratitude and respect."

Funds from the campaign raised by the sale of Victory party packs and donations will be used to continue the charity's work with people who have served and continue to serve in the Armed Forces.
