From an earlier post
9G-MKJ (FORMERELY SAA CARGO COMBI ZS-SAR WATERBERG) REGISTERED IN GHANA. BASED THERE AND IN LUXEMBOURG, NOT ZIMBABWE.MK CREW MOSTLY ZIMBABWEAN THOUGH, STRONG HISTORICAL LINKS TO THAT COUNTRY
doubleu-anker - What have the UK CAA to do with this aircraft ?
IMHO - sfa !
If it was a G-reg, and a UK operator (AOC/OS) fair do's then the UK CAA would be responsible for the operational oversight, but a Ghana 9G-reg, based in Ghana and Luxembourg
The only action the UK could take is through the Ministry of Transport who have powers under ICAO Annex 6, International Air Transport to inspect foreign aircraft on UK territory
However if the country of registration, the aircraft/crew/operator are in compliance with Annex 6, then there is little that any other country can do to hinder right to land, take-off and transit another ICAO member country
