I want to know the answer to the following question:
In what year was royal assent last witheld in the UK?
All the background I'm provided with is that "Even after colonies such as Canada, Australia, New Zealand, the Union of South Africa, and Newfoundland were granted responsible government, the British government continued to sometimes advise governors-general on the granting of assent; assent was also occasionally reserved to allow the British government to examine a bill before advising the governor-general.". Is that enough to answer the question?
Answer: no
