Russian Planes May Be Detained In The United Kingdom
Russian planes owned or chartered by Russians would be prosecuted if they cross UK airspace, according to ministers.
Russian-owned aircraft are already barred from flying to the UK, but the latest measure is aimed at affluent Russians who charter private jets registered in a third nation.
The administration stated that the sanctions will be aimed at Kremlin insiders.
One plane at Hampshire's Farnborough Airport is already being investigated.
The Luxembourg-registered private plane is being seized by UK officials as part of an investigation into whether it is Russian-owned and carried a Russian passenger to the UK in violation of sanctions.
New commercial sanctions have also been declared by the government, prohibiting all UK exports of aviation or space-related technology to Russia, as well as associated services such as insurance.
Foreign Secretary Liz Truss said the latest penalties will cause more "economic damage to Russia and people close to the Kremlin" when she announced them.
She went on to say that the administration would keep supporting Ukraine and "try to isolate Russia on the world stage."
"We were one of the first countries to ban Russian aircraft, and today we are going even further by making it a criminal offence for Russian aircraft to fly in UK airspace," said Transport Secretary Grant Shapps.
