Just over five months after leaving the White House, Barack Obama is to make his first public speech.

The former president is to hold a town hall style meeting with students from the University of Chicago, where he taught constitutional law.

Mr Obama will re-enter the political fray after several months of rest and relaxation including spending time with Sir Richard Branson on Necker, the tycoon's private paradise in the British Virgin Islands.

There have been sightings of Mr Obama in recent months including in New York City, where he was visiting his daughter, Malia.
