MPs have complained of a "really odd smell" in the House of Commons - only for it to be revealed that an ill Scout on a tour of Parliament had vomited on the Government benches.
A couple of Lib Dem MPs took to Twitter to complain of the stink:
The incident happened late yesterday.
A spokesman for Lib Dem MP Stephen Gilbert said: "Stephen brought it to the attention of the doorkeeper and they have attempted to clean it three times.
"Unfortunately the smell still lingers."
A House of Commons spokesman said: "When children are given tours it's not an unusual occurrence. It's been given a deep clean and it will be cleaned again tonight."
