The government position is if you are a serving member of the armed forces you will be breaking the law [if you go to Ukraine to fight].
There were reports in a weekend newspaper about three members who had gone AWOL over the weekend. They will be breaking the law and they will be prosecuted when they return for going absent without leave or deserting.
For others, as the government travel advice is don’t go to Ukraine, we strongly discourage them from joining these forces. My experience from having been security minister is people who went off to join the YPG [the Kurdish militia fighting in Syria] and other organisations: it didn’t end well.
It is also the case that, as a number are now discovering, the Ukrainians are very clear: you turn up, you are in it for the whole game. You are not in it for a selfie and six weeks, you are in it for real.
I think we have already seen some people at the borders find that may not be the right option to follow.
