Euan Blair (born January 19, 1984, London), is the eldest son of British Prime Minister Tony Blair.

Educated at The London Oratory School in West London, Blair is currently reading for a BA in Ancient History at Bristol University, having failed to achieve the required grades in his A-levels to secure his place at Oxford University.

Blair was found drunk by police in the South-Eastern corner of Leicester Square at the age of 16, after a night celebrating his completion of his GCSEs with friends.

In 2002 a scandal (sometimes dubbed Cheriegate ) was uncovered over Euan's mother, Cherie Booth, using allegedly under-hand methods to acquire two flats for him and his guards to live in Bristol.
