The Liberal Democrats will today unveil a poster attacking Boris Johnson for lying to the Queen, Parliament and the people.
Another poster will show Boris Johnson flanked by Donald Trump and Nigel Farage, stating: "Brexit is good for them, how is it for you?".
The posters are being launched in London this morning on four poster vans, that will then tour Conservative Liberal Democrat marginal seats that could deny Boris Johnson a majority.
Liberal Democrat Shadow Brexit Secretary Tom Brake said:
"Boris Johnson and his backers Nigel Farage and Donald Trump may stand to benefit from Brexit, but it is families across the country who will suffer.
"Johnson has shown time and again that he can't be trusted. He's lied to the Queen, he's lied to Parliament and he's lied to the British people.
"Now he is trying to dupe the public into believing that voting for him will make Brexit go away. This is the biggest lie of all and it must be challenged head on. His disastrous Brexit plan would mean years more uncertainty and damage to our economy, NHS and public services.
"Liberal Democrats have shown that we can stop Boris, stop Brexit and build a brighter future, by taking seats off the Tories across the country."
