Traduction de «keyser avait voulu » (Français → Anglais) :

Mais quant à la question centrale que Mme De Keyser avait voulu en quelque sorte privilégier, je crois qu’elle l’a mal traitée.
However, with regard to the central issue, to which Mrs De Keyser had wanted, in a way, to give preference, I think that she has dealt with it rather poorly.
