‘(Roy Jenkins) looked at the problem of Europe, as was his duty as a Member of Parliament, at first in strict relation to the advantages and disadvantages this would bring for his country, and at the same time took the mentality of his countrymen into account. […] Examinations of the conditions negotiated by the British Government convinced him that there were acceptable for his country, and so he stood firm in his views. When it came to the vote in the Lower House, all efforts to bring about a united negative attitude in his party broke down on his firm determination.’
