However, in 2003 Marek was de-selected by the local party and Griffiths was selected in his place. There followed a Labour Party inquiry, in which Marek was first contacted by telephone half an hour before the result was announced, and his de-selection was upheld. Marek then decided to fight to retain his seat as an Independent, and Griffiths struggled during the campaign; an early poll showed Marek beating her by 40% to 29%. In the event, on polling day Marek beat Griffiths by 973 votes. Subsequent elections Having been a supporter of Wrexham Football Club, Griffiths was elected to the board of the Wrexham Supporters Trust. In December 2005 she was selected again as Labour candidate for the Wrexham constituency for the 2007 Assembly elections. She benefited from high-profile support as the party saw an opportunity to recapture the seat; John Marek appealed to the large Polish immigrant population by translating his election material into Polish. However, Griffiths increased her numerical vote while Marek's vote fell, and she won the seat by 1,250. In 2011, Griffiths faced Marek for a third time, though by now Marek had joined the Conservatives. Both of them saw increases in their votes compared to 2007, but Griffiths held the seat with an increased majority
