I am sorry this man has got into this situation yet I have asked myself why he has 5 children to provide for and looking for work in Thailand when he has or had far more chance of that in the UK.
My conclusion is that the man is irresponsible.
The parents are left in a difficult situation for sure .
Even if the man is taken to the UK , will that change anything for the children he is responsible for? . I doubt that to be perfectly honest.
He has become a liability for all around him .
