Florentino Perez has been in charge at Real Madrid since June 2009

Real Madrid president Florentino Perez staged a tense press conference in which he argued with journalists and called for elections following a trophyless season.

Perez insisted he will stand again and spoke of an "organised campaign" against his leadership, telling his opponents not to "move in the shadows" and to instead contest the election.

His announcement comes after Barcelona defeated Real Madrid in the Clasico at Camp Nou on Sunday to claim back-to-back La Liga titles with three games to spare.

"I'm here to say I'm not going anywhere and I'm here to stand for election," the 79-year-old told the gathered press.
