Who is property’s Gail Trimble?

If you witnessed the Oxford student’s masterful performance on University Challenge recently, you will no doubt be eager to see four of the industry’s finest – Mike Slade, Francis Salway, Ian Coull and this magazine’s editor, Giles Barrie – battle it out to be crowned ‘Property Boffin’.

The event on Wednesday 18 March, organised by Sainsbury’s and Property Week, is in aid of Comic Relief. Around 200 of you will be able to see the quiz – and quizmaster Liz Peace doing her best impersonation of Anne Robinson – in person at Sainsbury’s HQ in London’s Holborn.

The £40 ticket price will go to Comic Relief and donations are, of course, encouraged.

If you’re not lucky enough to be there, you can still get involved by emailing a question for the combatants: further details at www.sainsburyspropertyboffin.co.uk. If your question is used, you will win a mystery prize.

My question is: which of the four of you owes the most amount of money to the bank?
