Palestine Action – the extreme activist group that infiltrates and vandalises military sites and defence firms - is to become a banned terrorist organisation. But very little is known about its members or supporters.

The Crime Agents host and LBC crime correspondent Andy Hughes went along to meet them as they protested outside Downing Street on the day MPs voted to proscribe Palestine Action. He spoke exclusively to former Labour MP Zarah Sultana, who this week quit to form her own party with Jeremy Corbyn.

Andy and co-host Neil Basu, ex-head of UK Counter Terror Policing, debate whether members of Palestine Action deserve to be classed as terrorists.

Andy and Neil also take your questions in this bonus Q&A episode.

In the very first episode of The Crime Agents, investigative journalist Andy Hughes reveals exclusively how hundreds of convicted terrorists have been released from UK jails over the past two decades, and are now living among us, many of whom continue to refuse deradicalisation treatment.

His co-host on the Crime Agents is the former Head of Counter Terrorism for the Metropolitan Police, Neil Basu. In this episode Neil explains how law enforcement go about catching terrorists, how terror plots are thwarted, and why there are now so many convicted terrorists no longer in jail.
