Erm the monarch held no power as head of state during the war years - the few remaining symbolic powers were just that - symbolic. Victoria was the last to actually use one after she was essentially backed into a corner by Palmerston not naming a replacement PM, despite months of avoiding in parliament. That was the mid 1850s.

Now, had you mentioned that a good proportion of the pre-war Tory party were Nazi sympathisers you might be on to something. Notably including Halifax who was offered the premiership before Churchill, after Chamberlain resigned.
