The "emergency brake" has now been officially proposed! The principle, put simply, is that the UK would be able to stop EU nationals from claiming work related benefits on the basis that the welfare system was under significant strain.
The implication is therefore that EU migrants are to blame for this strain on the system (as non-EU migrants are not entitled to public funds in any event). These are the same migrants who pay in 34% more in tax than what they take out in benefits.
What will be truly interesting to see is how this "emergency brake'" will be viewed in the UK. Is this the solution to the 'EU question'?
