Fiona Wood, from Kinross, went right down to the wire but secured a win with lassitude.
A forensic accountant is the first woman to become Countdown champion in 26 years. The long-running numbers and words game show, which has been on Channel 4 since 1982 when the broadcaster launched, has not had a female champion since 1998.
The match between Fiona Wood, from Kinross, and Chris Kirby went right down to the wire, but the accountant prevailed by getting the final conundrum: lassitude, meaning a state of physical or mental weariness.
Fiona, 50, said: “I decided to apply after (host) Colin (Murray) appealed for older contestants with (lexicographer) Susie (Dent) adding that they wanted more women. I have absolutely no regrets about applying and would encourage other women to give it a go.”
Following appeals from Murray and Dent along with mathematician Rachel Riley, applications from women have soared, Channel 4, said with insiders hoping more applications will follow on from Ms Wood’s win.
“Fiona delighted us all and gave us one of the very best moments in our 42-year history,” Dent, who has appeared in the “dictionary corner” since 1992, said.
“This series also reminded us how much Countdown is a show for everyone, and we would encourage anyone who loves the game to apply via countdown channel4.com.”
During the episode, Mr Kirby was let down when when he tried to get an eight-letter word score with “promotee”, over Ms Wood’s “promote”, but was told the result was not in the dictionary.
Mr Kirby came back by succeeding in another words round with “routeing”, and they both were unable to manage adding up the right amount during the numbers section, and were shown the correct answer by Riley.
They continued to match each other, even getting the same word “opiates” during the tense 90th series final. At the end, Ms Wood’s score was 96 to Mr Kirby’s runner-up score of 89.
After being presented with the trophy, she said: “I just can’t believe it. I’m not known for being decisive, and I thought long and hard before I decided to apply, and I’m just so glad that I did.”
The guest in the studio was actor and 2007 I’m A Celebrity…Get Me Out of Here! winner Christopher Biggins, who called the finale “magical”.
Last year, Northern Irish TV presenter Murray was named the permanent host of Countdown, taking over from former The Weakest Link host Anne Robinson.
