A dogged campaigner for non-proliferation

CHIEF nuclear inspector Mohamed El Baradei, the winner of the 2005 Nobel Peace Prize, has grown over the years into a dogged campaigner for non-proliferation.

The Egyptian diplomat has led the International Atomic Energy Agency during its transition from a nondescript bureaucracy monitoring nuclear sites worldwide to a pivotal institution at the forefront of disarmament efforts.

Austere and methodical, he has taken a sometimes strident line while guiding the Vienna-based agency through the troubles it has faced since the end of the Cold War.
