Sorry but when politicians deliberately spread misinformation that they know not to be verified and checked IS lying to public.
very much like tax evasion and tax avoidance, just because you have a flashy accountant and solicitor does not make it any less wrong.
It might not make it any less wrong, morally speaking, but it does, however, make it difficult to prove legal accountability (except in the case of tax evasion). And that's what they rely on.
