Boris Johnson has slammed Keir Starmer's Brexit reversal plan, saying MPs will be "walking into a hail of machine gun fire" if they attempt to overturn the 2016 referendum.

The former Prime Minister argued in a column in the Daily Mail that a growing number of Labour MPs want Starmer gone as the party sinks to a record low of 14% approval.

Boris explains that Labour MPs want Starmer to commit to a massive U-turn by making Labour the pro-EU party. The problem they face is that they don't believe Starmer is the right man to lead the Rejoin campaign - partly, but not limited to, how he swore at the last election that he would not try to reverse Brexit.

"If Labour MPs try to reverse Brexit they will be walking into a hail of machine gun fire - and if that's the fight they want, bring it on! But they should heed my warning before things get bloody..." wrote Boris on MailOnline.

This week, the House of Commons voted to begin talks with the European Union about creating a new customs union with the UK - a move that could begin the reversal of Brexit. It comes after Labour Deputy Prime Minister David Lammy said the UK would be better off if it rejoined the customs union, which it left as part of exiting the EU.

Most Labour MPs abstained in the Commons vote, but 13 voted in favour of the UK holding talks with the EU while just three voted against. A total of 100 MPs voted in favour, including Liberal Democrat, Green and SNP MPs.

"He can try to cover up the damage Labour is doing to Britain, by claiming (falsely) that it is all thanks to that 2016 vote," wrote Boris. He pointed to discredited promises, unnecessary tax rises, "many charges of lying" and Wes Streeting failing to fix the NHS.

Boris, who led the Leave campaign, highlights how the UK has not suffered the post-Brexit catastrophe some Remainers predicted. Rather, we have "grown faster than Germany and several other EU countries."

The Conservative politician suggested that the UK should try to attract global investors instead of raising taxes and hammering wealth creators so hard that they leave the country.

Finally, he criticised Labour's decision to cancel the Rwanda policy only to act shocked when tens of thousands continue to cross the channel.
