A Twitter campaign has begun to show Labour members' support for their beleagured leader - but not everyone is convinced.
After The Observer reported 20 shadow ministers had demanded Ed Miliband go, people began tweeting #webacked, showing their party's support for him, despite a catalogue of terrible headlines and rumours of a coup brewing.
But Mr Johnson told The Sunday Times him becoming Labour leader was a "definite no-no".
He said: "I am not keen to do it. We can win with Ed as leader and I can help him do that. That is why I'm staying on because there is a lot to be done and there is hope for the future if we can regain the trust of the British people.
"I'll help them out. I will do my bit and people will get sick of me on the media in the run-up to the general election."

So there's a rumour that 22 Tory MPs want Cameron to go, yet MSM is all about the Miliband rumours. Nice to see such balance. #webackEd— Amy. (@thisisamy_) November 9, 2014
But the hashtag was not just used by people declaring their support, many opposed to Labour winning the next general election joined in to wish the party well in sticking with Miliband. One joked: "Never interrupt your enemy when he's making a mistake."
Ok that's enough #webacked RTs now, I'll stop pisstaking. Because as Napoleon said "Never interrupt your enemy when he's making a mistake."— Angela (@mizzaggie) November 9, 2014
One journalist pointed out that, "if you need a hashtag to save your political career, it's already over."
Bemused by people who say #webackEd is evidence of his support. If you need a hashtag to save your political career, it's already over.— Brett Leppard (@TheBrettLeppard) November 9, 2014
This guy also pointed out something a bit awkward.
On Sunday, Gordon Brown's former spin doctor Damian McBride claimed Mr Miliband's camp would "fold" if a serious challenger put themselves forward.
He told Murnaghan on Sky News: "If anyone was prepared to come forward now and actually do a formal challenge I think the Miliband camp would fold very quickly.
"Ed Miliband has very little hinterland within his own party and that's very dangerous," he added. "That was the thing that made Gordon Brown survive plots and coups and it made Tony Blair very resistant."
He added: "I think it is extraordinary that there is not a member of the Shadow Cabinet out today defending him."
Mr McBride said that Mr Milband has "fluffed" the opportunities he has had to restore his authority.
"It's when you fluff those opportunities that you get yourself in more trouble."
