Michael Adebolajo, 29, and Michael Adebowale, 22, ran over Lee with a car before hacking him to death.
Adebolajo said he was a “soldier of Allah” and the murder was an act of war.
The animals were found not guilty of attempting to murder a police officer.
The jury of eight women and four men took around an hour and a half to reach their verdict.
