How many British divisions were ready after the fall of France?

Was only one division ready to fight in Britain after the fall of France?

Readiness was changing, and usable brigades did not necessarily appear as complete divisions, making that fixed count misleading.

The claim that only the First Canadian Division was combat ready is rejected as too simple. Readiness changed as formations reorganized and replaced lost equipment. Counting complete divisions also leaves out brigades that could be available for fighting. A useful count therefore needs a date and a clear distinction between divisions and brigades.
