David Cameron and his Tory Party are really plumbing the depths in the debate on the Reform Treaty. Cameron's article for this morning's Sun was rabid and riddled with untruths.

In particular, his claim that the Reform Treaty would "transfer power from our elected Parliament to the EU's unelected bureaucrats" is a flat out lie. In fact the opposite is the case. The Reform Treaty specifically increases the power of elected parliaments not bureaucrats by increasing the role of national parliaments and the European Parliament. It strictly limits EU action to the policy areas agreed by Member States in the treaties. Mr Cameron has either not read the Treaty or has no understanding of its contents - perhaps not surprising since he is too arrogant to meet with his right-wing counterparts in Europe.

He talks about Gordon Brown's "shameless arrogance" as being a "big cancer eating away at trust in politics". On the contrary, it is Cameron who is displaying shameless arrogance by telling lies to the British people.

Cameron's dishonest assertions follow on from William Hague's barmy claim that the Reform Treaty would see the EU take Britain's seat on the UN Security Council. This is simply not true.

Cameron thinks that he is a "euro-realist" and pledged to create a new-centre right group in Europe which would include the Czech Prime Minister Mirek Topalenek's Eurosceptic Civic Democrat Party. But the Czech PM is refusing to hold a referendum on the Reform Treaty as it does not create any new powers for the EU. Topolanek's stance speaks volumes about the Tories' opportunism and obsessive Europhobia.

David Cameron and his party seem to be pursuing a policy of 'little Englander' isolationism that would greatly damage Britain's national interests. For a man who hopes to become Prime Minister, his tactics and arguments on the Reform Treaty have been gutter politics of the highest order.
