That was an awful interview. Reid seemed more interested in proving her own purity and decency than letting Caroline talk and subsequently came across as a finger wagging headmistress on a "you've let the school down, you've let yourself down..." lecture.
She could have asked questions in an impartial fashion rather than telling Caroline her view was that she'd been very naughty.
Mind you, that's how the pair of them seem to conduct things. It's hardly illuminating if GMB is just basically What Piers and Susannah's Very Important Opinions are this morning. Esp as neither are that bright.
