BORIS JOHNSON is a liar and a sexist, Labour charged today after the PM refused on live radio to apologise for derogatory comments about single mothers and women. 

His car-crash LBC interview came as pressure mounted on the prime minister to come clean over decades of sexist, homophobic and racist remarks. 

Today’s outrage came when Mr Johnson was challenged about an article he wrote in 1995 where he blamed single mums for “producing a generation of ill-raised, ignorant, aggressive and illegitimate children.”

When pressed to apologise during the morning interview by a caller named Ruth, the PM claimed his words had been “distorted.”  

Labour’s shadow education secretary Angela Rayner, who became a mother when she was 16, said Mr Johnson’s “hateful” comments meant he was “not fit to be an MP, let alone Prime Minister.”

"He tried to deny what he wrote, but the evidence is there in black and white for us all to see, proving once again that he's a liar as well as a sexist,” Ms Rayner blasted. 
 
“According to Boris Johnson, when I was a young single mum, I should have been pushed into 'destitution on a Victorian scale'.”

In the unearthed Spectator articles, Mr Johnson also wrote that it was “outrageous that married couples should pay for the single mothers' desire to procreate independently of men” and suggested that a way should be found “to restore women's desire to be married.” 

Scrambling to save face, Mr Johnson told LBC’s Nick Farrari that he’d written “millions and millions of words in the last 30 years” that “people can cull” to use against him. 

He also blamed the Labour Party for “trying to distract from the reality that they have no plan to get us out of the EU,” instead of apologising. 

The radio caller, who was raising two children on her own when Mr Johnson’s article was published, said her children had “suffered the stigma attached to the comments Mr Johnson made at the time.”

She also questioned the PM on why he takes such an interest in other peoples’ families when he refuses to speak about his own. 

On the show, Mr Johnson declined to disclose how many children he has or how involved he is in their lives. 

Today’s interview coincided with demands from Labour that Mr Johnson answer 60 questions related to offensive comments made during his journalist and political career. 

Questions in the Time to Tell the Truth pamphlet include: “Do you still think global warming is a ‘primitive fear without foundation’?”; “Do you still call gay people ‘tank-top bumboys’”; “Do you still think a man should ‘take control of his woman’”; and “Will you apologise for saying young people had ‘an almost Nigerian interest in money’?” 

Mr Johnson has also come under increasing pressure to explain why he keeps ducking out of interviews. 

He was branded a “coward” by Labour MP Clive Lewis on Thursday for failing to show up to a Channel 4 debate on climate change. 

Speaking about the no-show, Labour’s national campaign co-ordinator Andrew Gwynne said: “Boris Johnson may think he is born to rule but if he can’t face the people and tell the truth then he can’t govern the country.”
