Foreign Secretary Liz Truss has toughened sanctions on Russia further after Putin claimed economic measures amounted to “total war”, writes politicshome.com.

The latest ratcheting up of measures came after Prime Minister Boris Johnson said the west should continue to introduce sanctions until “every single” Russian troop had left Ukraine.

Truss said the latest sanctions would block sanctioned oligarchs from accessing UK aviation and maritime industries and engineers meaning they will be blocked from accessing technical assistance or repairs to aircraft and ships.

The Foreign Office said the new powers had already been used to sanction Russian businessmen Eugene Shvidler and Oleg Tinkov.
