Firestarters have launched an arson attack on a farmhouse at Princess Diana's home Althorp House, leaving her family devastated.

The late princess's brother Charles Spencer revealed news of the blaze at the Northamptonshire estate on X, formerly Twitter.

Diana had lived at Althorp from the time of her parents' divorce to her marriage to the Prince of Wales, now King Charles, in 1981.

A private island situated in the centre of Althorp's Oval Lake is where she was buried after her death aged 36 in a Paris car crash in August 1997.

Earl Spencer today shared pictures of the fire damage, commenting: 'Stunned to learn that one of ⁦@AlthorpHouse⁩’s farmhouses - fortunately, unoccupied at the time - was apparently burnt down by vandals last night.'
