The Prime Minister will be grilled by viewers for 10 minutes on his plans for the future of Britain during a live Q&A session on Facebook. The showdown will take Mr Johnson out of his comfort zone of the House of Commons and head-to-head with British voters online. The off-the-cuff interview will be a stern test for the Prime Minister who is renowned for going off script - so expect fireworks.
Number 10 officials are understood to be concerned the event may turn into a car-crash with another Q&A yet to be scheduled.
An adviser to Mr Johnson said: “Let’s, erm, see how this one goes.”
However others have welcomed the move and denied he is following the lead by the US President Donald Trump.

A source close to Mr Johnson told The Telegraph: “This isn’t like Trump because Trump hides from the mainstream media whereas Boris is constantly out and about doing walkabouts.
“This is about doing something simple and direct.”
The new strategy by Number 10 is a clear indication of the influence of Mr Johnson’s senior advisor Dominic Cummings.
The mastermind of the 2016 Vote Leave campaign is a keen advocate of data and the use of social media to reach voters.
This is not the first time Mr Johnson has taken to social media since becoming Prime Minister.
Last week the Prime Minister recorded a 2 minute broadcast and reiterated his proposals to put an extra 20,000 police officers on the street, as he begins a major crackdown on crime.
The video was watched by almost 200,000 people.
This afternoon, Mr Johnson is likely to address his latest plans for Brexit amid growing hostility towards his strategy to deliver the UK’s exit from the bloc.
Speaker of the House of Commons, John Bercow, issued a stern warning to Mr Johnson and warned he “will fight with every breath in my body” to stop the Prime Minister suspending parliament to deliver Brexit on October 31.
Mr Bercow told a 200-strong audience at the Edinburgh Festival: “The one thing I feel strongly about is that the House of Commons must have its way.
“And if there is an attempt to circumvent, to bypass or – God forbid– to close down Parliament; that is anathema to me and I will fight it with every bone in my body to stop that happening.
“We cannot have a situation in which Parliament is shut down – we are a democratic society.
“And Parliament will be heard and nobody is going to get away as far as I am concerned with stopping that happening.”

Meanwhile the Prime Minister also faced a fresh attack on his “do or die” Brexit pledge by former Chancellor Philip Hammond, who said a no deal Brexit would be a “betrayal” of the 2016 EU referendum.
Mr Hammond wrote in The Times: “Most people in this country want to see us leave in a smooth and orderly fashion that will not disrupt lives, cost jobs or diminish living standards, whether they voted Leave or Remain in 2016.”
Mr Hammond added: “Parliament faithfully reflects the view of that majority and it will make its voice heard.
“No-deal would be a betrayal of the 2016 referendum result. It must not happen.”
Boris Johnson will be live on Facebook at 12.15pm.
