An armed forces charity has revealed its fears that the efforts of brave World War One soldiers may be forgotten after a survey revealed one in five millennials thought Britain fought it against France.

SSAFA, formerly known as the Soldiers, Sailors, Airmen and Families Association, polled 2,000 British adults over some of the war’s pivotal moments.

It found that millennials were not aware who the British Prime Ministers were during the War, with nearly half (42 per cent) believing wrongly that Winston Churchill held office.
