 Daniel Hannan pointed out that the Prime Minister, Tony Blair had twice promised a referendum on the matter, to which Blair replied that he had promised a referendum on the European Constitution rather than the Lisbon Treaty, which unlike the former was not a constitutional treaty.In early October 2007, the Commons’ European Scrutiny Committee had found that the treaty was “substantially equivalent” to the rejected constitution.In mid October 2007 Bill Cash tabled an Early Day Motion calling for a referendum on the treaty, with 47 supporting signatures.
