"Britain had 420,000 military personnel killed in WW2 (I am not including the numbers from India, Canada, Australia, New Zealand in this figure).
France had 245,000 military killed."
Incorrect.
UK military personell deaths 383,600
Total civilian and military deaths: 450,700
French military Deaths: 217,600
Total civilian and military deaths: 567,600
I think you've attempted to add the civilian deaths to your total for the UK. Misuse of figures again, tut tut, seems to be a recurring habit amongst those that are pro leave.
It needs to be remembered that the French only fought in France and its invasion and the defeat of the Germans where as the UK fought in both the European war, the Pacific War, in which it lost 82,000 soldiers.
Then we need to include causalities lost in the North and East African campaigns.
I think overall we'd find that in the European war the UK lost about the same number of people as the French.
Misuse of facts and statistics does appear to be a recurring theme .
