The sinking of the Belgrano during the Falklands War was arguably the most controversial event during that conflict and one that haunted Thatcher for years. The Belgrano itself was an ancient bit of kit, launched in the 1930s, used by the US in WWII and then sold to Argentina in 1951. This would have been one of the last engagements for this warship had it not been hit by a missile fired from a British nuclear submarine.
The question that Thatcher struggled to answer – and we see her here getting an uncharacteristic roasting from a member of the public – was whether the Belgrano was sailing towards or away from the Falklands. Interestingly, Thatcher doesn’t claim that it was either inside the Exclusion Zone or even sailing towards the islands (in fact, she infers it was sailing away).
The Belgrano sinking became as notorious as the sinking of the Lusitania in WWI. That said, sympathy was in short supply among the majority of the population after the attack by Argentina on HMS Sheffield. But for the left, this issue became a stick to beat Maggie and this video certainly makes compelling viewing.
