The controversial new campaign from the pro-European Union party parodies the famous “Careless Talk Costs Lives” World War Two poster.

In the updated version from the Lib Dems, it warns that “Careless Votes Cost Lives”.

The original poster played a part of a major propaganda campaign by the British government during the Second World War.

It discouraged talking about sensitive material where spies could overhear it, showing either potential Nazi eavesdroppers or depicting a death caused by leaked information.

During a week of immense political uncertainty, the Lib Dems have mirrored the iconic poster using almost identical imagery.

The poster replaces the two gossiping diners in the original design with Boris Johnson and Jeremy Corbyn, both of whom the Lib Dems claim have worked together to deliver Brexit.

The poster’s warning, “Careless Votes Cost Lives”, sits below the two politicians.

Analysis of voting records revealed that Corbyn ordered his MPs to abstain or vote with the Tory government on over 30 key Brexit votes.

To highlight this, the pro-European party are launching a city-wide poster campaign to warn against ‘careless votes’ for Labour and the Conservatives.

Liverpool Lib Dem leader Richard Kemp and North West MEPs Chris Davies and Jane Brophy revealed the posters in Liverpool today.

Doubling down on the poster’s message, Richard Kemp described his party as “unapologetically pro-European” and willing to do “absolutely anything” to stop Brexit.

He said both voters and politicians should think carefully about how they vote in the coming months, warning of “careless votes facilitating a Brexit disaster.”

Speaking at the launch, Kemp said: “On more than 30 occasions, Corbyn has ordered his MPs to vote with the Conservatives to deliver Brexit.

“There can be no coming back from that, and both MPs and voters must recognise the repercussions of their votes.

“If you are happy with Brexit destroying our NHS, crashing our economy and wiping out millions of jobs, then vote for Labour and the Conservatives.

“But do so knowing that Boris Johnson and Jeremy Corbyn will use your vote as a mandate to deliver exactly that – no matter the consequences to you and your family.

“Only the Liberal Democrats are determined to stop Brexit, no matter what. Lib Dems will fight until the very bitter end if we have to.”

North West MEP Chris Davies added: “Labour have voted with the Tories more than 30 times to deliver Brexit. They do not want to stop Brexit, so do not waste your vote on them.

“Only the Liberal Democrats have been crystal clear on Brexit. We will do anything we can to stop Brexit including revoking Article 50 on day one of a Lib Dem majority government.

“It’s what’s right for the North, and it’s what’s right for the country.”

Last week, the Lib Dems gatecrashed Jeremy Corbyn’s rally in Liverpool with a van circling the venue with an electronic billboard carrying the slogan: 'You can't stop Tory Brexit with Labour Brexit. Only Lib Dems will stop Brexit.'
