Are UK labour party officials salaries public record? If so, how do I
find them? If you can get to them and I can't then I'll pay more for
some specific salaries of officials. Also, I'm interested in listings
of fees paid to consultants during campaigns.

The nearest I can get is from the Electoral Commission.
 
Register of campaign expenditure. Use the drop down boxes to obtain
information on specific areas of expenditure. It is difficult to
identify where fees paid to consultants would be placed.

I do not know if such detailed information has to be released.
