Jeremy Corbyn said the clip showed Johnson "just doesn't care" about the sick child, while Angela Rayner branded him "an utter disgrace".
The NHS is an extremely emotive subject for British people, most of whom have a loved one who has depended on it for treatment. During this election campaign, the NHS has been a key topic of discussion, with Labour accusing the Tories of opening the NHS up to privatisation post-Brexit and the Conservatives denying it.
During the clip, Johnson repeatedly tries to steer the topic from the NHS towards Brexit. But when repeatedly asked to look at the photo, he eventually takes the reporter’s phone.
People are furious with Johnson’s response. Many have branded the prime minister “heartless” and “disgusting”.
This is absolutely incredible.
