Hillary Clinton 'not sure' about running for presidency

She has been named one of the most powerful women in the world and Hillary Clinton is showing no signs of slowing down.

Since stepping aside from her role as US Secretary of State, she has been working on a memoir describing her years in the job.

The book, 'Hard Choices', was released last month and covers everything from sparring with Vladimir Putin to her part in bringing down Osama Bin Laden.

Naga Munchetty met Mrs Clinton and asked if rumours were true that she may run in the 2016 US presidential election when Barack Obama stands down.
