can boris do that emergency power thing to overrule the fixed term act?

no duh, country of origin

the best way to make people leave is to remove the incentives that made them come in the first place. People who have moved once will move again

you think the majority of migrants move once drop roots and stay forever?

then you've never met any. Most people have either lived in one country all their lives or they've lived in 3+

because what brought them is gone and they are the type of people who look for opportunity

so theyll look elsewhere

well the only solution is genocide then

if thats your thinking there is only one solution

the reasons people do anything are the same as murder, motive and opportunity. People who have moved once are clearly people who are looking for motives, ie benefits elsewhere

make opportunity easier, cheap flights agreements with countries for residential status to be granted etc then you'll have floods of people leaving
