Ministers should start campaigning for Europe's new constitutional treaty, says Denis MacShane.

The Europe minister tells the FT that although there was considerable anti-European feeling in British politics people were unlikely to vote to isolate themselves from the rest of Europe.

On the eve of a visit to Britain by Jacques Chirac, MacShane compared the relationship between Britain and France to that of a sometimes bickering married couple but said they were "on the same wavelength".
