Kirsty Young's castaway this week is the broadcaster and journalist John Humphrys. For 21 years he has been at the helm of Today, Radio 4's flagship news and current affairs programme. Millions of devoted listeners enjoy his tenacious interviewing style - and it's won him a healthy respect from politicians too. Not all are supporters though; Jonathan Aitken accused him of "poisoning the well of democratic debate" - an attack which he initially thought would cost him his career.

Now, his life is dominated not only by the alarm bell - which is set for 3.58am - but by his youngest son, Owen. When John Humphrys describes the joy and warmth the seven-year-old has brought him, he becomes, if only temporarily, lost for words.
