Mahyar Tousi of mahyartousi.co.uk/ has done an excellent job on this, though he isn't a Christian he has great insight into politics around the world. In this video he exposes the flipflopping government of Boris Johnson getting involved with the EU Covid vaccine passport scheme. I can just hear Sturgeon's Scottish Government lavishing at the thought of being in some part of the EU.
For us, as Christians this is surly a step towards the Revived Roman Empire of the European Union. This is where the prophet Daniel and John in the book of Revelation write about that would come in to pass in the tribulation days that is launched the by Antichrist.
