Shareholders of Tokyo Electric Power Company (Tepco), which operates the crippled Fukushima nuclear power plant, have approved the nationalisation of the company, BBC News reported.

The government will put 1tn yen ($12.6bn; £8bn) into the utility company to prevent its collapse.

It brings its support for Tepco to at least 3.5tn yen since last year's earthquake caused a reactor meltdown.

Protesters outside the meeting demanded the company abandon nuclear power.

There was hot debate at the shareholders' meeting as to whether Tepco should restart its nuclear reactors, although a motion to scrap all seven reactors at Tepco's Kashiwazaki-Kariwa plant, which is the world's biggest nuclear facility, was defeated.

Shareholders also questioned Tepco's proposal to raise household electricity prices by 10% because of rising costs.

It needs to buy more oil and liquefied natural gas while all of its nuclear reactors remain shut.

Prime Minister Yoshihiko Noda said it was crucial to ensure that Japan's economy would not be affected by the lack of electricity, but public opinion remains split and anti-nuclear activists made their voice heard at Wednesday June 27 meeting.
