Boris Johnson has insisted his Government will deliver greener vehicles than his campaign bus.

The Prime Minister unveiled his Mercedes-Benz Tourismo bus, which uses diesel and AdBlue, at a small rally with Conservative activists in Greater Manchester.

It has the slogan: “Back Boris and vote Conservative to… Get Brexit Done.”

It also has a tagline saying: “A stronger economy to invest in our NHS, schools, police, infrastructure.”

A small amount of text reading “emergency exit break glass” can also be seen, but this is a safety measure connected to the bus rather than a Conservative slogan.

Mr Johnson emerged via the emergency exit and described it as a “wonderful” bus.

He added in a speech to Tory activists that there will be “buses that are a lot greener than this”, once his party has implemented its “fantastic” policies.

Mr Johnson also said: “Some of you may be asking, why do we even need a bus, why do we even need an election?

“The answer is because Parliament is unfortunately paralysed.”

Mr Johnson repeated several lines of attack on Labour leader Jeremy Corbyn, adding: “Come with us and get Brexit done, or waste more time and more of this country’s precious, precious economic future on another referendum and yet more dither and delay.”

His bus was built at the Mercedes-Benz factory in Hosdere on the outskirts of Istanbul, Turkey.

It was first registered in February and meets the latest EU emissions standards.

Critics of Mr Johnson regularly highlight the bus he used during the 2016 EU referendum, when touring the country for the Vote Leave campaign.

This red bus claimed £350 million was sent to the EU each week by the UK, adding: “Let’s fund our NHS instead.”

The figure and commitment of how much money would be spent on the health service were disputed.
