Sir Terry Pratchett, fantasy author and creator of the Discworld series, has died aged 66, eight years after being diagnosed with Alzheimer's disease.

"The world has lost one of its brightest, sharpest minds," said Larry Finlay of his publishers Transworld.

The author died at home, surrounded by his family, "with his cat sleeping on his bed", he added.

Sir Terry wrote more than 70 books during his career and completed his final book last summer.

He "enriched the planet like few before him" and through Discworld satirised the world "with great skill, enormous humour and constant invention," said Mr Finlay.

Some very sad news...
