Donald Trump has responded to Mitt Romney’s call for him to release his tax returns in characteristic fashion, saying the 2012 nominee was “one of the dumbest and worst candidates in the history of Republican politics”.

The outspoken front-runner was responding to Mr Romney’s assertion on Wednesday that there was “good reason” to expect a “bombshell” in the billionaire’s tax history.

“I think there’s something there,” the former Massachusetts governor told Fox News. “Either he’s not anywhere near as wealthy as he says he is, or he hasn’t been paying the taxes we would expect him to pay or perhaps he hasn’t been giving money to vets or to the disabled like he’s been telling us he’s been doing.”
