Labour has bought up all the advertising on a Conservative supporting website to push the message that Tory MPs ought to dump Boris Johnson.
The Conservative Home website, which acts like an online newsbox for Tory members, has been plastered with Labour adverts.
The image, taken from the government's lockdown-era public service messages, is a face-on portrait picture of a masked-up medic and asks: "Look into her eyes and tell her you still support Boris Johnson."
