His father is a GP and his mother is a surgeon. He has one elder brother. He went to Eton from 1993-98. Iain graduated from Cambridge University in 2003 with a first class degree in History. He worked for a year in Westminster - at Vote 2004 and the private office of Michael Howard - before pursuing a full-time career as a journalist. Vote 2004 was described in the Sunday Telegraph as the "most successful political campaign of all time". Iain was runner-up in the Guardian Student Media Awards as Columnist of the Year. While at university he also founded and edited The Cambridge Slapper - a popular satirical magazine.
His first novel, Twenty Something: The Quarter-life Crisis of Jack Lancaster was published in 2006 by Gerald Duckworth and Company Ltd. The book won him the 2006 infamous literary Bad Sex in Fiction Award, which he accepted in person announcing "I hope to win it every year".  He is the youngest author to have won the somewhat dubious honour. This book has also been translated into Vietnamese by Le Thu Thuy, under the title "Tung qua tuoi hai muoi", and was well received by young Vietnamese readers. Overall the novel was well received, drawing critics' comparison with Sue Townsend, Helen Fielding and Tony Parsons.
