A video of Mr Miliband, the Labour Party's Shadow Business Secretary, accusing Mr Johnson of seeking to "get Brexit undone" in the House of Commons has gone viral. The former Labour leader warned MPs that passing the legislation would "equip the Government with the power to break the law" and was a matter of "right versus wrong" rather than "Leave versus Remain". The 25-minute-long video being shared on social media is not the full clip but a segment which focuses on Mr Miliband's direct attack on the Prime Minister sitting just a few feet away.
Sitting as the country's leader escaped Mr Miliband after he lost Labour the 2015 election to the Conservative's David Cameron.
He became party leader in 2010 after Gordon Brown lost to a Tory-Liberal Democrat coalition following Labour's decade in power under Tony Blair.
Three years after his election defeat during an interview with former Labour spin doctor Alastair Campbell, for GQ, Mr Miliband revealed what had helped him to overcome the immediate feelings of defeat.
Mr Campbell said: "Do you ever get over the loss?"

Mr Miliband replied:: "I've moved on now but it took a good year I think.
"The 2017 general election was an inflection point, a sort of movement of moving on, partly because the last election was not my election.
"And also, there were some things I was clear about when I lost - I wanted to carry on being an MP, I felt I could still make a contribution.
"I felt there were big things that mattered about the future of the country, about the things I'd been talking about like inequality, what the post-financial settlement was going to be for Britain.
