Cardinal Jorge Mario Bergoglio caught the world's attention two years ago when he became Pope Francis.

In that time he's sought to bring a new era of openness, consultation and humility to the Vatican.

He was named pontiff after Benedict became the first pope to resign in 600 years instead or ruling until he died.

In an interview with Mexican tv to mark the second anniversary of his rule Pope Francis says he has no plans to keep the job for life either. 

"I have the feeling that my pontificate will be brief, four or five years, even two or three. Two have already passed. It's a somewhat strange sensation. I say maybe not but it's the psychology of he who plays and thinks he's going to lose, so that he won't get upset but then will be happy if he wins. I don't know what it is but I have the feeling that the Lord has placed me for a short time, but it's just a feeling so I have the possibility open."

The 78 year old pontiff said Benedict shouldn't be considered an exception.

At the same time he said he wasn't in favour of an automatic retirement age for popes.
