YouGov did a poll on this
This figure is higher than the number who say they would either volunteer or accept conscription - although if the British mainland were under threat more would be willing to fight

The biggest score was those who would not fight and would refuse to be called up.
I think this is the right trying to do the 'reds under the bed' scare. If you look at what is actually happening, Russia cannot even beat Ukraine, but suddenly, according to Generals etc they are going to attack Western Europe. Their casualty rate is high from Ukraine and they even had to promise prisoners a pardon if they joined the forces but somehow, according to these clowns, they are going to steamroller over Europe. Utter BS.
