British Prime Minister Boris Johnson came under fire on Monday for his response to being shown a photo of a sick child lying on a hospital floor ahead of the Dec. 12 election.

Later during a campaign visit, he was taken to task by a voter who challenged his Conservative Party over a spoof website to distract voters from the opposition Labour Party's policy program.

Johnson's Conservatives are leading Labour in opinion polls, with Brexit and the future of the country's public health service the two most prominent campaign issues.
