Meet the Author: James Barr

In this week's Meet the Author, the BBC's Nick Higham speaks to author James Barr about his new book A Line In The Sand.

The book vividly tells the story of the short but crucial era when Britain and France ruled the Middle East.

Barr says he believes the book shows that world leaders should question "how deeply to get involved in the internal politics of these countries - it is not always to everyone's benefit".
