Monte dei Paschi shares fall after Italian referendum result

World's oldest bank is seen as most at risk from economic fallout of Prime Minister Matteo Renzi's poll defeat

Shares in MPS, which was founded in 1472 , fell amid fears the resignation of Prime Minister Matteo Renzi will affect its attempts to clinch a a5bn (4.2bn) lifeline from investors.
