"Candidate   Keir Starmer         Rebecca Long-Bailey         Lisa Nandy
Popular vote         275,780             135,218                79,597
Percentage          56.2%                   27.6%                  16.2%

Given that Starmer received more votes than the other two candidates combined any comparison to the referendum vote is irrelevant.

Just someone trolling and flame-baiting it would seem.

As always it is best to ignore.
