I want to know the answer to the following question:
Who persuaded the king to lock the wine cellars during WWI?
All the background I'm provided with is that "To the King's later regret, David Lloyd George persuaded him to go further by ostentatiously locking the wine cellars and refraining from alcohol, to set a good example to the supposedly inebriated working class.". Is that enough to answer the question?
Answer: yes
