Outgoing British Prime Minister Tony Blair has revealed he has worn the same pair of shoes to his weekly question-and-answer session in Parliament since becoming the country's leader in 1997.

The shoes in question, an 18-year-old pair of hand-made leather brogues that have only been re-soled once, were made by Church's in Northampton, central England.

"I know it's ridiculous, but I've worn them for every PMQs (Prime Minister's Questions), I've actually had them for 18 years," Blair told The Times in an interview, adding that "cheap shoes are a false economy."

According to a spokeswoman for Church's, a 134-year-old company, the shoes Blair bought would have cost 150 pounds ($353) when he bought them, and cost about 290 pounds ($682) now.

Blair is due to officially resign as prime minister next Wednesday (local time) and will appear at Prime Minister's Questions in the House of Commons for one last time - most likely in his lucky brogues.
