One of the suggestions is that belief in conspiracy theories is strongly linked to mistrust of the government. It perhaps makes sense that those who are politically opposed to the current government are more likely to mistrust its 'official version' narrative.

Would be interesting to see if this changes after a change of government next election.

It could also be that those inherently mistrustful of government and officialdom are more likely to be conspiracy theorists.
