^^ There are NO guarantees that any new terms are going to be upheld regardless.
When a migrant who used to receive benefits see's them reduced under the new plan and takes their case to the European court of human rights, I wonder what will happen ..
I migrant can go to the ECHR even if Britain leaves the EU, because guess what, the referendum isn't about leaving the ECHR but leaving the EU. There is no discussion or referendum about leaving the ECHR.
Perhaps you should actually read up on what the EU referendum is about before making your decision to vote?
