Laurence and Jackie Llewellyn Bowen

Laurence and Jackie Llewellyn Bowen once played in February 11, 2006 on the UK version of the show for a Celebrity Valentine's Day special. They were originally ruled to have given a wrong answer to their £1,000,000 question, but the question turned out to be a bad question, so they were asked to return and try for another £1,000,000, but this time, they decided to walk with their £500,000.

Jackie and Lawrence's Run to the Million (Partial)
After 14 questions, they reached the £1,000,000 question which was:

It was later found out that the question was flawed. "One out of many" was the original motto of the United States, and it did have Latin origins, but since 1956, they have also been using "In God we trust," as a national motto, but it did not have Latin origins, so the question was ruled out as a bad question, and Laurence and Jackie were invited back for another £1,000,000 question, which was:

Trivia

 * They are the first and only celebrity pair in the UK to reach the final question, even though the question turned out to be bad.
 * They are the last contestants to have ever won £500,000 on the British version of Millionaire.
 * Their run was not repeated on Challenge, likely due to the bad question turning out to be a bit controversial to show after the original airing.
 * They were the first ever contestants in the UK version to answer the £1,000,000 question incorrectly. However, Chris announced that they were given another chance of winning the million; they then walked away with £500,000 after they chose not to answer their second million pound question.
 * No other contestant on the UK version of Millionaire had ever lost £468,000; the most money ever officially lost was £218,000, which occurred only twice: Duncan Bickley in October 2000, and Rob Mitchell in October 2003, when they answered their £500,000 questions incorrectly and fell from £250,000 down to £32,000.
 * They are the only UK contestants to appear on a bad question that is not worth £64,000, the second ones and pair to appear on a bad Top Prize question in the world, after Ling Wing Kuen and Ling Shuk Ling (in Hong Kong), and only the second UK celebrity contestants to appear on a UK bad question.

Goofs

 * When the Llewellyn Bowens were revealed to have lost £468,000, the £500,000 lose cue was played instead of the £1,000,000 one.
