This position was supported by Home Secretary Theresa May, who said in March 2014 that passport checks should be introduced if Scotland adopted a looser immigration policy.
Taj je stav podržala i Theresa May, britanska ministarka unutrašnjih poslova, koja je u martu 2014. izjavila da bi se morale uvesti pasoške kontrole u slučaju da Škotska počne da sprovodi labaviju imigracionu politiku.
