Tony Smith CBE spent his career managing our UK border controls, from junior immigration officer to Head of the UK Border Force. He spent more than four decades in the front line of the conflict between those who argue for open borders and free movement and those whose focus is on building barriers. He played a prominent role in managing security on both sides of the Atlantic after the 9/11 attacks in North America. Along the way he has worked constantly to make controls more efficient, better informed and fairer, yet less vulnerable to abuse. After retirement in 2013, he became a prominent media spokesman on border control issues, from tackling legal immigration crime, human smuggling and terrorist travel to managing borders through Brexit and beyond. This is his story.
