Load of rubbish. The U.K. has been trying for years to get a free trade agreement with the US. Nobody is targeting Apple but if they keep breaking the law they will keep getting sanctioned. The courts are independent of government in the U.K.
The CMA exists and routinely engages in ethically questionable (and potentially illegal) behavior. See their borderline criminal efforts in Microsoft's acquisition of Activision and their illegal collusion with the FTC in America to try and force their Sony-sponsored case through our courts.
