Toshiba chief resigns over scandal

Toshiba's chief executive and president Hisao Tanaka has resigned after the company said it had overstated its profits for the past six years.
He will be succeeded by chairman Masashi Muromachi, with vice-chairman Norio Sasaki also stepping down.
On Monday, an independent panel appointed by Toshiba said the firm had overstated its operating profit by a total of 151.8bn yen ($1.22bn, £780m).
The overstatement was roughly triple an initial estimate by Toshiba.
The company's business empire stretches from home electronics to nuclear power stations.
"It has been revealed that there has been inappropriate accounting going on for a long time, and we deeply apologise for causing this serious trouble for shareholders and other stakeholders," the company said in a statement.
"Because of this Hisao Tanaka, our company president, and Norio Sasaki, our company's vice chairman... will resign today."
Mr Tanaka told a media conference that "we have a serious responsibility", adding that the company would need to "build a new structure'' to reform itself.
Mr Tanaka, 64, and Mr Sasaki, 66, both joined Toshiba in the early 1970s.
Mr Sasaki served as Toshiba president between June 2009 and June 2013, covering most of the period during which the firm inflated the profits.
Atsutoshi Nishida, an adviser and former chief executive from 2006 to 2009, also gave up his post.
Mr Tanaka and his predecessors are among eight high-level executives who have now resigned after the independent report found senior management involved in a scheme to inflate profits over several years.
People took to social media to express their concern at the scandal.
