Cardinal Peter Turkson's journey from Ghana to Vatican

Pope Benedict XVI's successor is being chosen by 115 cardinal-electors during a secret election - known as a Conclave - in the Vatican's Sistine Chapel.

Africa's leading candidate for Pope is 64-year-old Cardinal Peter Turkson who is also the Vatican's peace and justice office.

Peter Turkson became the first-ever Ghanaian cardinal in 2003 when he was appointed by Pope John Paul II.
