Yes I know about Freudian slips (Freud actually called them parapraxes and I've read the original discourse). But I don't think Sunak said incompliant, which would indeed be the opposite of compliant, I think he said in compliant, two words, which means the mistake was not the opposite but incorrect part of speech, compliant instead of compliance, and wouldn't be a Freudian slip. Also in the heat he wouldn't have had time to correct it, if he even caught it himself.
