Edmund de la Pole, Earl of Suffolk, is executed. A potential claimant to the English throne due to his Plantegenet ancestry, he had been attainted in 1504 after he attempted to gather an army for an invasion. Henry VII had taken him prisoner from Philip of Burgundy on the understanding that he would guarantee his safety, but Henry VIII did not feel bound to this agreement, anxious at the threat he might pose while the king was out of the country campaigning in France.
