Translate the following English sentence to French:
"This 'no' vote will, first of all, mean that our friends and brethren in Sweden and Great Britain will also vote against and, secondly, it will send out a crucial signal to the summits in Feira and Nice to the effect that one ought to be guided by the terrain, which is more important than the ideological map."
Non seulement nos frères et amis suédois et britanniques diront également "non", mais ce refus sera également un signal capital lancé à l'intention des participants aux sommets de Feira et de Nice selon lequel il faut suivre le terrain. Le terrain est plus important que la carte idéologique.
