As Pakistan went to polls on Monday, Bilawal Zardari Bhutto, chairman of the Pakistan People's Party, remained at his alma mater Christ Church College in Oxford to concentrate on his studies.

"Bilawal is in Oxford, busy with his studies," Wajid Samsul Hasan, his guardian and former Pakistan high commissioner to the United Kingdom, said.

Bilawal, who was appointed chairman of the PPP after the assassination of his mother and former prime minister Benazir Bhutto, has said he would take part in active politics only after he completes his studies.
