NICOLA Sturgeon has been urged to “follow Boris’s lead” by pledging to use the knock-on £100 million windfall - from the Tory frontrunner’s pledge to create 20,000 new police posts south of the border - to create nearly 2,000 officers in Scotland.

Mr Johnson, in his latest pledge to woo over Conservative members, said his plan for 20,000 more bobbies on the beat in England and Wales would reverse the decline in numbers since 2010 and increase the total number to more than 140,000 by 2022.

“Soaring crime levels are destroying lives across the country and we urgently need to tackle this,” declared the former London Mayor.

“To keep our streets safe and cut crime, we need to continue to give the police the tools they need and crucially we need to increase the physical presence of police on our streets. That’s why I will be increasing police numbers by 20,000. More police on our streets means more people are kept safe.”

He added: “We want to make sure we keep the number of police officers high and we need to keep visible frontline policing. That’s what we did in London and that’s what I want to in the whole of the UK to cut crime and keep people safe.”

Colin Clark, the Conservative MP for Gordon, who is supporting Mr Johnson’s campaign, said: “This announcement goes to show how in touch Boris is with the concerns of people across the UK.

“I hope now that the SNP welcome Boris’s strong announcement with one of their own. The SNP should follow Boris’s lead. The extra money through the Barnett Formula would mean almost 2,000 more officers pounding the beat in Scotland.”

Meanwhile, the BBC announced that Andrew Neil would conduct two consecutive half-hour interviews with the candidates in a special programme at 7pm on BBC One on Friday July 12.

Fran Unsworth, the Director of BBC News, said: “Andrew Neil is one of the best political interviewers on television.

“He’ll be questioning the two candidates on behalf of audiences up and down the country, including the Conservative Party members who are voting for their next leader. Their decision will, of course, affect all of us, so it’s strongly in the public interest that we put the two candidates and their policy ambitions to the test.”

Tomorrow, the two candidates will take part in the party’s Scottish hustings in Perth.

Earlier, Jeremy Hunt shared a picture of an automated email he had received from the Johnson campaign, asking him for support for his campaign.

"Well this is awkward...definitely didn't sign up to this mailing list," he tweeted.
