BBC Breakfast presenter Naga Munchetty left Health Secretary Matt Hancock floundering after pointing out a major issue with the government's new track and trace scheme.
The new system launched today at 9am and answered questions about it on video link today.
However, when he appeared on the BBC news programme this morning, Naga appeared entirely unimpressed with his response to a question she posed regarding whether it was mandatory.
She probed him on whether it was mandatory for the public to pass on the contact details of those they had been in contact with.
Revealing that she had viewers had been in touch with their own questions, Naga said: "Angela has been in touch and she’s asking about test and trace.
“She said, ‘I’m not comfortable passing on my contact’s contact details if I have them or anyone passing on mine. GDPR nightmare.’
“So what would you respond to that? I have a couple more as well.”
The health secretary initially stumbled upon answering the question, but eventually replied: "Well, I think in the same way that you are contacted by the NHS now and you are asked about another symptom or disease, you talk to them about it.
"There are very strict confidentiality rules that are in place, both under GDPR and the medical system has its own system of confidentiality as well.
"And, actually in practice, we have found only a tiny proportion of people have that sort of reaction."
Naga raised her eyebrows and responded pointedly: "Erm, I don’t think many people want their phone numbers handed out."
He replied: "Well, all I can tell you is that in the lived in experience of the pilots and past when this has been done by Public Health England is that a very small proportion of people react in that way.”
