I can't say for sure if this is the strangest parliamentary question asked in recent years but, via John Rentoul, it's certainly rum. John Spellar, Labour MP for Waring submitted this as a written question:
Mr Spellar: To ask the Secretary of State for Health whether he plans to ban the sale of (a) tea and coffee with sugar and (b) cheddar cheese sandwiches in hospitals. 
Anne Milton: No.
UPDATE: In the coments, Guto Daffyd has a good theory as to what this might be about.
