Jeremy Paxman asks the questions as teams of distinguished university graduates compete in a festive version of the quiz.

The first match is between the University of Reading, with BBC weather presenter Jay Wynne and writer Joan Smith, and Emmanuel College, Cambridge, with writer and comedian Rory McGrath and broadcaster Mary-Ann Ochota.

Another first round match sees distinguished graduates from two of the UK's top universities battle it out for a place in the semi-finals.

The University of Keele, with Steve Jackson, co-founder of Games Workshop, and Dr Maggie Atkinson, Children's Commissioner for England, plays the University of Aberystwyth with MPs Elfyn Llwyd and Dan Jarvis.
