Johnson and his family went back to England soon after he was born because his mother needed to take her Oxford finals. Johnson's sister Rachel was born a year later. As a child, Boris Johnson had severe (bad) deafness. He had many operations to have grommets put in his ears. He was reportedly quite quiet as a child. He was educated at the European School in Brussels, Ashdown House and then at Eton College. At Eton, he was a King's Scholar. He read Classics at Balliol College, Oxford. He was a Brackenbury scholar. He was also elected President of the Oxford Union at his second attempt (try). Radek Sikorski said that Johnson acted as a supporter of the Social Democratic Party to win the Union presidency. This was because the party was popular at the university. Johnson denies he did this. He said he was only the SDP's preferred candidate. Along with David Cameron he was a member of Oxford's Bullingdon Club. The club is a student dining society known for its raucous feasts.
