“May I be perfectly candid? I also am still a Unionist in this sense. If I were certified of twenty years of unbroken power in this country, I am still most clearly of opinion that the solution of the Irish question which would be best for England and best for Ireland would be the prosecution during that period of the policy which, in our opinion at least, had attained so large a measure of success in the year 1906. In saying this I make it quite plain that I am conscious that there are many of my colleagues—there must be many of my colleagues—who would not take that view. You must make the reservation that you are given that power and that you are given that power for the requisite period. The late Lord Salisbury spoke of "twenty years of resolute government." The Unionist Party, in the period to the close of which I refer, had been given some ten years, and it was only given those ten years by what many members of this House would describe as the accident of the issue, with its repercussion on the Election, of the war in South Africa. That accident and that Election gave the Unionist Party some ten years of office. Is it not evident, in trying to descry what lies in front of us through the mists of the future, that no man living can claim that twenty years, or anything like twenty years, lie in front of any Party that believes in the maintenance of the relations between Ireland and this country on the lines that have existed since the passing of the Act of Union?”
