MADRID, Nov 7 (Reuters) - Real Betis president Jose Leon tendered his resignation to the majority shareholder Manuel Ruiz de Lopera on Tuesday to set in motion a presidential election at the struggling Primera Liga club.'I have placed my position in the majority shareholder's hands but will continue in my post so that there is no power vacuum,' Leon told a news conference. 'I hope everything will be resolved harmoniously between the candidates who want to come and be president here.' Leon had been in the post since the beginning of July only when De Lopera stepped aside after 14 years at the helm, though the latter remained a controlling influence behind the scenes. Leon's decision added to the air of uncertainty round the club who are in the relegation places in the league after nine games. On Monday the board gave coach Javier Irureta their qualified backing following Sunday's 3-2 defeat to Villarreal which dropped them to 18th place in the table. Betis, who sold two of their best players, winger Joaquin and striker Ricardo Oliveira in August, are without a win in eight league and Cup games. They host Recreativo Huelva in a King's Cup fourth round, second leg on Wednesday and follow that with a home match against Levante in the league on Sunday.
