Neither party will give up on the UK's aerospace industry and the F-35 is more important to the UK for that, than an military asset.
I wasn't aware of any serious calls to abandon the F-35 in the UK - from any party. Confusion? not really.
The Netherlands is a special case, their budget is seriously screwed up and they are no indication of what will happen elsewhere.
South Korea is interesting. Apparently the airforce had predetermined they wanted the F-35 and went through the motions of having a competition.
