If you know your Web Summit from your European summit, and your Project Eagle from your Apple tax case, you might like to try your luck with this year's Christmas Quiz and be in with a chance to win a pair of flights from Dublin to London, courtesy of Irish airline CityJet, along with a two-night stay for two people in The Marylebone, a Doyle Collection hotel. The runner-up will receive six bottles of wine.

Today marks the last day that eligible entries can be received, so get your brain out of its Christmas induced fog and try a hand at the quiz. You can find the 30 questions here.

Entries should be sent for the attention of Ciarán Hancock to bizquiz@irishtimes.com. The winner will be announced next week.
