Let me get this right. The remember Diane, who really never did anything but have children, BUT, WWII and Winston Churchill is irrelevant.
Trust me mate, having gone through the UK school system: It was obsessed with WW2. Churchill was never really mentioned because everyone did (and still generally do) know all about him. If changes have been made they will just have been to refresh the curriculum. Please don’t believe sensationalist stories in the UK tabloids on these issues.
