Dear Barclays Bank manager

Although you've never bothered to ask me why I've closed my accounts with you after more than 30 years, I'll tell you anyway. It's nothing to do with your staff, who have always been ready with help and advice. It started when I found out that Barclays was lending money to Mugabe's henchmen, despite a European embargo on supporting that murderous regime.

To add insult to injury, when confronted, Barclays didn't even deny it or try to defend their sanctions-busting. They merely explained the loophole that let them get away with it (they were incorporated in Africa before the embargo). Like that would make us all go: "Whew! Oh, well that's all right, then. No harm done there."

Bastards. Sadly, I can't stop them doing it. But I can stop them doing it with my money.
