BORIS Johnson is the “voice of the majority of the Scottish people,” Downing Street has claimed.

The bizarre comment from the Prime Minister’s official spokesperson came as more questions were asked over the ousting of Luke Graham, the former Scottish Tory MP in charge of the No 10 Union Unit.

It emerged last night that he was being replaced by Vote Leave chief and Dominic Cummings’s protege, Oliver Lewis.

Known as Sonic, the aide is set to take control of Downing Street’s campaign to save the Union – despite having no known experience of Scottish politics.

Graham’s departure also means that there are now no Scots in the Union Unit.

His sacking was prompted by a furious row after the Prime Minister’s gaffe-filled visit to Scotland last week, according to Sky News.

“Oliver Lewis needed a new job and he wanted Luke’s. He’s an old pal of Boris’s from Brexit days so he got the job,” a source close to Graham told The Times.

“It’s the problem with the Union in a microcosm. Someone in Whitehall thinks they can sort it out, so they kick out the Scot who probably knows about it.”

Speaking at the daily lobby briefing, the Prime Minister’s official spokesman confirmed Graham has “left his No 10 position”.

“The No 10 Union Unit will continue to support the Prime Minister in his capacity as the Minister for the Union,” the Prime Minister’s official spokesman said.

“We don’t comment on details of personnel matters but the Union is an incredibly important focus of the Prime Minister and the No 10 Union Unit will continue to support him on that.”

Asked whether No 10 was now on a war footing ahead of a battle with Nicola Sturgeon’s SNP, the spokesman said: “As the Prime Minister has said himself, he thinks all parts of the Union are stronger together and he will be and continue to be the voice of the majority of the Scottish people who voted to keep the UK together.

“He will always stand against those trying to separate the UK which is why it remains an important focus.”

Just two days ago, Johnson’s press secretary Allegra Stratton said Graham was not leaving, despite rumours. “That is not my understanding,” she told journalists.

“Luke Graham is the head of the No 10 Union Unit. It’s a team within the wider policy unit and he’s a very, very, very valued member of staff.”

One source told Sky News that Graham had done “an excellent job”.

They said: “Oliver needed a role and he’s seen this as the next big thing. The PM trusts him and he has some radical ideas with a new direction.

“It allows time between now and May to set up a longer-term strategy on this and think bigger than Scotland.

“Luke is a party man and cared a lot about not seeing the Tory party diminish in Scotland.”

Another Whitehall official said: “Luke Graham has improved the focus of the government on delivering for Scotland and all parts of the UK and has helped ensure communications focused on demonstrating the practical value of the Union to people in all parts of the country.”

Though other sources were less kind. One said: “He didn’t endear himself to other [special advisers], ministers or civil servants.

“No-one was weeping to see him go”.

The SNP called it a “Vote Leave takeover of Boris Johnson’s taxpayer-funded anti-independence campaign”.

The party’s deputy leader in Westminster, Kirsten Oswald, said the move would “drive up support for independence even further”.

She added: “By installing Dominic Cummings’s Brexit apprentice as head of the so-called ‘Union Unit’ the Prime Minister is demonstrating, yet again, that he is completely clueless about Scotland.

“This botched Tory plot also raises serious questions over the misuse of taxpayer funds for political campaigning.

“It’s clear the Tories are using public money to build a party political campaign team in the run-up to the Scottish Parliament elections.”
