Sir Iain Duncan Smith has been a Conservative MP for more than 30 years, and led his party from 2001 to 2003.

In parliament he’s a vocal contributor on defence, security, and international issues. 

His criticism of China’s government is so vocal the country has placed sanctions against him and his family.

He tells Sitrep why he believes China is a threat to the UK, not just a ‘challenge’ as it is officially deemed, how his military service shaped his political ambitions, and whether he’d join the “too small” armed forces of today.
