As we've remarked before relations between Germany and Poland are a little strained at the moment. They're in the midst of a number of different rows at the moment which are likely to overshadow Angela Merkel's trip to Warsaw today.
So it probably hasn't helped that the Polish government "expert" on bilateral relations with Germany has attacked Merkel in the Berliner Zeitung for knowing "little about Poland". He wrote: "We are dealing with a country whose national policies are essentially egotistical and not exactly friendly towards Poland."
PS - for all those following the negotiations on the Constitution, the Kaczynski’s advisor on European issues Marek Cichocki has said that Poland will not accept attempts to bring back the voting weights that were in the Constitution. He wrote in a Polish newspaper editorial that: “Poland will never resign from the votes in the council given under the Nice voting system, because it is a fundamental instrument of real influence in the internal and external policies of the union."
The last time Poland tried to block the Constitution in 2003 it very quickly met with threats that a flow of subsidies would be cut off by large member states. Once again we seem to be heading for a head-on collision.
