Boris Johnson is set to announce plans for a security crackdown next month, making it a criminal offence not to declare work in the UK on behalf of a foreign government, according to the The Times.

A response to the Intelligence and Security Committee’s (ISC) report last year into allegations of Russian interference in British politics the move would force all foreign spies to reveal themselves.

The Home Office has confirmed plans for a central register in a bid to counter hostile spy activity, with the Government vowing to be “resolute in defending our country, our democracy, and our values from such hostile state activity”.

Getting spies to reveal themselves is just one part of the plan however. An update to the Official Secrets Act so it can be used on foreign state actors, such as cyberhackers is also set to be announced.

The news comes as relations after Foreign Secretary Dominic Raab said the UK Government “stands in full support” with the Czech Republic authorities who published photos of two men identified as Alexander Petrov, 41, and Ruslan Boshirov, 43.

Speaking of the two, Mr Raab said: “We are as determined and committed as ever to bring those responsible for the attack in Salisbury to justice, and commend the actions of the Czech authorities to do the same”

Petrov and Boshirov are said to be linked to a huge ammunition depot explosion in the town of Vrbetice in 2014, and are wanted by police in the UK after the Crown Prosecution Service authorised charges against them in connection with the attempted killing of Sergei Skripal in Salisbury on March 4 2018.
