If Britain had uncovered Quisling's German contacts

What might Britain have done if it had discovered Quisling's meetings with German leaders before the invasion of Norway?

Britain would probably have mobilized sooner, although Quisling's marginal position meant the contacts revealed more about German intent than Norwegian political control.

Evidence of Quisling's December 1939 contacts with German leaders would probably have prompted a rapid British mobilization. Quisling was far less influential inside Norway than his later notoriety suggests. In an illustrative anecdote, Oslo's police chief did not recognize him when he demanded the government's arrest and nearly had him expelled before German protection was available. The warning could expose German intent without demonstrating that Quisling possessed a functioning domestic apparatus capable of delivering Norway.
