Best ways to find public company biggest shareholder list which is accurate

Hey all,

I'm not a beginner of investing, but one problem which I sometimes have is finding out largest shareholders of a company.

For example if I want to find out Nokia's biggest share holders there will be many sites that say different things.

I know for a fact that BlackRock is the owns the largest percentage, but it was really hard the list where it was mentioned because most of the lists only had solidium on top or only institunional shareholders.

What is the best page to find the real DEAL list so I don't have to waste time on many sites.

Or is it really this difficult for public companies?

Please help me and thank you on advance.
