Seems this is no easy task and because governments are short termist they just make impossible promises to the electorate to win enough votes to be in power for the next 4/5 years.
The home office is not fit for purpose, we need a new department that can tackle this problem effectively and humanely, the best working model would be to process refugees in Europe, but this would mean having a much stronger working relationship with EU members, and stopping illegal claims then and there whilst letting genuine refugees through. This means refugees would have safer routes, gangs wouldn’t have as much involvement, and there’d be no more tragedies in the channel.
Not my idea specifically, many have floated those idea before but it will probably take longer than 4/5 years so a short termist government will probs just apply a sticking plaster.
