From Mr Radek Sikorski, Mr Maciej Olex-Szczytowski and Mr Jacek Rostowski.

Sir, European Union solidarity was excellently, if belatedly, demonstrated to President Vladimir Putin by Angela Merkel, the German chancellor, and José Manuel Barroso, president of the European Commission, at the recent EU-Russia summit at Samara in central Russia. Thoughts of renewing a comprehensive EU-Russia partnership agreement must be quelled until Russia stops its egregious harassment of its EU neighbours.
