Some dozy cow has offered the following ''insight''
What is ''a joke''?
That's how the system works - the country seeking assistance, in this case the UK, asks the host country, in this case Portugal, to carry out investigations on it's behalf. They don't get to wander in jackbooted fashion all over someone else's turf. And of course they pay for it. Would you ask someone to pick up something for you while they are out shopping then refuse to pay for it?
So what's the problem?
