The episode title – It’s a Khanderful Life – tells us pretty much all we need to know about this Christmas special, which finds busybody Mr Khan seriously dissatisfied with the way his life has panned out.

Enter an angel in the shape of Lynda Baron, and a tour through Khan’s life as it might have been, and we have pretty much a comic re-run of Frank Capra’s 1946 classic in miniature.

And in colour!
