Sociopath

No empathy. Witness him ignoring Reeves in tears at his side. A human being would have consoled her.

No sense of humour.

No affect.

No inner life (doesn't read, do art - openly admitted so).

Bristles when challenged.

Hates being laughed at (viz. TV audience at his “Son of a toolmaker” spiel) – which he has not repeated since having been unable to stop saying it previously..

Pathological liar. As confirmed by a former SPAD (Starmer is "a hollow man, who cannot stop lying...").

Refuses to take responsibility for things that happened on his watch..

"It never crossed my desk"... ad nauseam

Grandiose. Preening at international gatherings, cringe making wearing of military garb when he can. Yet nothing he does at any of these whatevers makes any difference to anything

No soul. Look into his eyes. Nothing there. The eyes are where we see another.
