The Finance Minister is characterising the Taxpayers' Union campaign against her as childish

The TPU's sent MPs Nicola Willis-branded fudge - saying she favours sugar-hit policies rather than real spending cuts.

It's produced an AI advertisement using a likeness of her image and voice - criticising her economic track record.

Willis says if it spent more time on savings instead of designing fudge, it could contribute usefully to public debate.

She says if people want to be juvenile, that reflects more on them than her.
