More successful Allied operations in Norway 1940

If somehow Britain and France had been more successful and defeated the Germans in Norway, what happens next?

Assuming Hitler hasn’t been kicked out by the generals, would he risk an invasion of France?

If he does and it goes as in the OTL, what happens when German forces are on the English Channel, does the UK abandon Norway?

Without a Norway fiasco, does Chamberlain stay on for longer as PM?

What would be the Soviet reaction to a more successful British/French Norway campaign?
 
The Reich would just have to try again, cause ports in Norway for the U-boats to disrupt trade with the Soviet Union was essential to Barbarossa.
