Former MPS chief executive questioned by prosecutors Vigni probed in derivatives scandal at Italy's 3rd largest bank

(ANSA) - Siena, February 6 - Former Monte dei Paschi di Siena (MPS) chief executive Antonio Vigni entered a prosecutor's office in Siena on Wednesday for questioning into alleged fraud at the troubled bank.



MPS, Italy's third-biggest bank, was thrown in crisis in January when it emerged that a shady series of derivative and structured finance deals produced losses of 720 million euros.



There have also been reports of bribery and corruption by bank officials regarding, among other things, the costly nine-billion-euro acquisition of rival Antonveneta in 2008.
