Gladstone had become personally committed to the granting of Irish home rule in 1885, a fact revealed (possibly accidentally) in what became known as the Hawarden Kite.
The decision led to a serious factual error in the Bill, a mistake over the calculation of how much Ireland should contribute to the British Imperial Exchequer.
The error was discovered during the Committee Stage of the Bill's passage through the Commons and forced a major revision of the financial proposals.

Some historians now suggest that Gladstone was the author of his own defeats on home rule, with his secretive drafting alienating supporters, and enabling serious flaws to appear in the text of his bills.
