Who are the Brits trying to fight in Ukraine and could they do more harm than good?

ITV News - What You Need To Know

Who are the untrained Brits who have defied official advice to head to Ukraine? What’ll happen to them if and when they come home? And could they end up doing more harm than good?
UK Editor Paul Brand has been filming with people who have travelled from the UK to the Polish border to volunteer to defend Ukraine and in this episode tells ITV News Presenter Lucrezia Millarini what you need to know about their good intentions but obvious limitations as fighters.
Paul explains why the consequences of defying official advice not to travel may be very different for AWOL soldiers to the civilians who have headed over to fight and also why their presence on the frontline may ultimately inadvertently play into Russia's hands.
