MATT Hancock has been condemned for urging a Labour MP to alter her “tone” after she pressed the UK Government on failures to roll out sufficient Covid-19 testing.

The Health Secretary made the comment during questioning in the House of Commons.

Shadow cabinet minister for mental health Dr Rosena Allin-Khan – who has been working as an A&E doctor during the coronavirus crisis – put the Health Secretary on the spot after the UK’s death toll became the highest in Europe.

She asked if Hancock acknowledged that many frontline workers believe a lack of testing “has cost lives”.

The Health Secretary flatly dismissed the concerns and encouraged Allin-Khan to adopt a less critical tone, as he feels shadow health secretary Jonathan Ashworth has done.

Hancock replied: “No I don’t. I welcome the honourable lady to her post as part of the shadow health team. I think she might do well to take a leaf out of the shadow secretary of state’s book in terms of tone.”

He added: “I’m afraid what she said is not true – there’s been a rapid acceleration in testing.”

Allin-Khan hit back at the Tory minister on Twitter.

“I will respectfully challenge the Government – I want our country to succeed,” she posted. “However, I will not 'watch my tone' when dozens of NHS and care staff are dying unnecessarily.”

The Labour MP was backed by scores of social media users, who condemned Hancock’s offhanded approach.

Piers Morgan said it was Hancock who needed to watch his tone.

Sky News correspondent Alex Crawford critcised the Tory’s “bizarre” response.

Doctor and author Rachel Clarke accused Hancock of sexism.

The hashtag #everydaysexism was soon trending on Twitter as dozens of high-profile accounts hit out at the Tory minister.

Comedian David Baddiel also condemned Hancock. He tweeted: "There is no 'tone'. @DrRosena  asks a completely straightforward question in a completely straightforward manner and @MattHancock's tells her off, as if she's been rude or shrill or perhaps even just a woman asking a difficult question."
