For just over a decade Bertie Ahern was Taoiseach of Ireland, the second longest serving prime minister in the country's history. Bertie became one of the key players to bring peace to the troubled North, helping to negotiate the historic Good Friday Agreement. He also oversaw Ireland's economic revival and the emergence of the so-called Celtic Tiger. But the man once called the "Teflon Taoiseach" has become unstuck, being forced to resign amid ongoing questions about his personal finances last year. He has written all about it in his autobiography.
