Boris Johnson was expertly trolled by a woman while on the election campaign trail who made a "love child" joke.

The Prime Minister - who has a reputation as a womaniser- has faced repeated questions about the number of children he has.

In the clip, which was filmed as part of a BBC documentary on Brexit, a woman tells Mr Johnson:  "My son looks remarkably like you, I'd just like you to see him."

He begins to look at the picture on her phone but when she says "he could be your love child" the PM determinedly avoids engaging with the woman instead telling the crowd "stick with us" before he is whisked away and escapes the situation.

Rumours have continued to swirl about the Prime Minister's family life.

While appearing on LBC during the election, the PM refused to answer repeated questions about his children, saying it wasn't what voters wanted to talk about.

She said "my son looks remarkably like you..."

Mr Ferrari probed him, asking: "How many children do you have?

"Are you fully involved in all their lives?

"Can you tell me there's not another Johnson on the way?"

But Boris replied: "I don't think this is what the nation wants to hear! The nation wants to hear how we are going to deliver Brexit …"

Before the brutal signoff. Boris Johnson tried to ignore the woman's comment

Boris Johnson split from wife Marina Wheeler. The couple, who married in 1993, have four children together - Lara, Milo Arthur, Cassia Peaches, and Theodore Apollo.

But he has had multiple affairs, including the one with Petronella Wyatt which led to a pregnancy that was terminated.

And a 2013 court ruling said the public were entitled to know about claims that one affair - with art consultant Helen Macintyre - resulted in a daughter who was his.

The child's family had sought to stop the father being named.

But the Court of Appeal said: “The core information in this story, namely that the father had an adulterous affair with the mother, deceiving both his wife and the mother's partner and that the claimant, born about nine months later, was likely to be the father's child, was a public interest matter which the electorate was entitled to know when considering his fitness for high public office."
