Tesla board 'too close to Elon Musk'

A group of Tesla shareholders has questioned the independence of the electric carmaker's board, warning it is too close to boss and co-founder Elon Musk.In a letter, they said the board was "largely unchanged" since the firm went public and at risk of "groupthink".They urged it to re-elect members annually and to add two new independent directors to the board.In a tweet Mr Musk said the investors "should buy Ford stock" instead.
