Your first sentence is nothing more than a phrase designed to keep the comrades' spirits up - at least if you don't flesh it out. And it still doesn't explain how the Leninist Party is possible in a place like Britain.
The CP's were by no means massive everywhere. In Britain, for instance, they had nearly 50,000 after the war, when there was a lot of good feeling about the role of the USSR in defeating Hitler. Prior to the war they were far smaller and in the period following it declined with each successive decade. Where the CP was big it was usually in places like France or Italy where a mass social democratic party like Labour didn't exist, and to a large extent they fulfilled the role of that mass social democratic party.
Furthermore, it is far too simplistic to say that they were 'controlled by Stalin.' For a variety of reasons the leadership and a majority of the membership willingly complied with the directives from Moscow and the leaders largely interpreted them in their own fashion. Interestingly, they did not see this 'Stalinism' as being in any way a departure from Leninism, but a development of it. When 'Stalinism' gave birth to Eurocommunism, many Eurocommunists in the CPs similarly did not see their politics as a departure from Leninism, but a development of it. The lesson: you can tell yourself that anything is Leninism at the same time as you try to square the circle.
