David Cameron was appalled last night to discover a leek in Number 10 Downing Street.
The leek was discovered in the kitchens of the Prime Minister's home.
"This is a travesty," said kitchen manager, Glen Williams. "I do not know how such a thing could happen in the most secure kitchen in the land. I take full responsibility."
Downing Street has very strict security measures that attempt to keep any Welsh influences out of the hallowed hall, having a leek in the kitchens is a major breach of this security.
"We think that a junior chef might be responsible," said Williams. "He may have been unaware of the need to keep leeks out of Downing Street, and been making a rabbit and leek pie. Or it might have been the fruit and veg delivery man, I've always thought he looks a bit shifty."
The hunt is now on to ensure that this is an isolated incident. MI5 have been brought in to sweep Downing Street for daffodils, carved wooden spoons and dragons.
"We did find a signed photo of Theo Paphitis," said Detective Inspector Jenn Darme, of the Met. "But we don't think he's a Welsh dragon."
Plaid Cymru have made a statement stating that they are upset about the lack of Welsh references at Downing Street, but are pleased that it has meant there is a Welsh story in the news.
"We've not had a Welsh story in the news since Huw Edwards stopped being a news anchor on the BBC," said David Jones, of Plaid Cymru.
