Does the Chinese Communist Party understand how our parliamentary democracy works? The evidence from the last 24 hours suggests not. Along with some of my Conservative colleagues in the House of Commons – Sir Iain Duncan Smith, Tim Loughton, Tom Tugendhat and Neil O’Brien – as well as two peers, a QC and an academic, I have been banned from entering China, had any assets in China frozen (not that I have any there) and have had Chinese citizens and institutions prohibited from doing business with me.
