Michael Palin has paid a touching tribute to his friend and Monty Python colleague Terry Jones who has been diagnosed with dementia.

Posting a message on Facebook Palin wrote the following:

"Terry J has been my close friend and workmate for over fifty years. The progress of his dementia has been painful to watch and the news announced yesterday that he has a type of aphasia which is gradually depriving him of the ability to speak is about the cruellest thing that could befall someone to whom words, ideas, arguments, jokes and stories were once the stuff of life. Not that Terry is out of circulation. He spends time with his family and only two days ago I met up with him for one of our regular meals at his local pub. Howard Johnson, an American friend of Python, was in town and took this picture. Terry doesn’t say very much but he smiles, laughs, recognises and responds, and I’m always pleased to see him. Long may that last."
