Possible Clues:

• Drunk swallowing cheese and last of Chardonnay — not an example of this!
• Calmness, gravity
• Reshuffle by Tories: that’s a serious state
• Not the condition of drunkard unknown to eat cheese?
• Restraint of drunk circling empty bar? That's unknown
• Property of a judge that's missing in Lords?
• Boris yet to exercise temperance
• Abstinence
• Avoidance of drink; calmness
• Starters of salads, omelettes, cheese and sides to take away? Presumably, it's not for those who are tight!
