Tory MP appears to propose a United States of Europe

According to Tory MP Daniel Kawczynski, the EU is just not strong enough and needs strengthening. In a piece for the Tory grassroots website ConservativeHome Mr Kawczynski argues that the EU:

"needs to become a bicameral institution, with an Assembly with Members appointed in proportion to population size, plus a Senate, with each state granted an equal number of Senators."

In other words the EU constitution should mirror the US constitution. The logical implication of this argument is that we should seek to create a United States of Europe. I wonder what some of Mr Kawczynski's colleagues will think about this?
