A senior figure at a major investor in Scottish infrastructure has warned that the creditworthiness of the country’s projects is at risk if it votes for independence.

Masashi Oda, chief investment officer of Japan's Sumitomo Mitsui Trust Bank's equity investment department, said: "If there is a major change in the way the market works or any regulatory bodies, then that'll cause concerns for any investors, including Japanese [ones]. If there are any changes involving currencies, that would definitely change the risk and creditworthiness of lending terms towards any Scottish project."
