Why Britain repeatedly passed over French combat aircraft

Why did Britain decline French aircraft such as proposed Mirage variants?

Other aircraft better matched British requirements and gave the United Kingdom more industrial participation.

Britain did not avoid French aircraft out of simple national prejudice. British requirements led to the F-4 Phantom, Panavia Tornado, and Eurofighter Typhoon because those programmes fitted the desired missions more closely. Domestic or collaborative programmes also gave British industry more design work, production share, and influence over future development. A French design had to outperform the aircraft and the industrial benefits attached to those alternatives. Combat-aircraft procurement is simultaneously a military and industrial decision.
