Plans have been drawn up for a full-blown United States of Europe over which Britain will have 'very little say', a Cabinet minister warned today.
The Prime Minister has promised that, as a result of his referendum reforms, Britain will not be sucked into an EU superstate.
But Chris Grayling, the leader of the Commons, pointed to a document signed last September in Rome by the speakers of the national parliaments in Germany, France, Italy and Luxembourg.
It says that 'concrete proposals' to deepen EU integration towards a 'federal union of states' will be drawn up at a meeting in Luxembourg next month.
