Venture capitalist group 3i Plc saw pre-tax profits flat at UKP156m for the year to March 31 and net profits sank by 82% to UKP41m, while the group’s level of investment grew by a mere 5% to UKP597m: chief executive David Marlow said 3i had established significant overseas business during the year by opening offices in Italy and Spain and through its new joint venture in Japan he remained confident but cautious about the group’s future growth.
