With its controversial six-month EU presidency coming to an end, the Czech Republic's eurosceptic President Vaclav Klaus made sure Saturday that the incoming Swedes knew what to expect from the Lisbon Treaty debate. 

Klaus said that the European Union was "squaring the circle" with guarantees granted to Ireland before its vote on the treaty.

"I find this amusing and above all undignified," Klaus, whose country holds the EU presidency until the end of this month, told Saturday's edition of the Pravo daily. "We all know that it's impossible to square the circle, but it is exactly what these countries have tried to do. To say that the concessions don't change anything about the Lisbon Treaty is silly," he added.

"Although it is written in the treaty that not all countries ... will have their own commissioner, now suddenly it is promised that they will," Klaus said. "Every normal human being, a first grade pupil, would know that it is a change and that somebody is promising it. So it is a change," he said.

The Czech president's comments were likely to open a debate on whether the treaty's ratification process should be renewed just over a week before Sweden takes the reigns.
