US automaker General Motors on early Monday confirmed the resignation of Rick Wagoner as chairman and chief executive officer of the company, and named Fritz Henderson, its current president and chief operating officer, as its new CEO.

In a short statement, the Detroit-based automaker said that "Rick Wagoner is stepping down as chairman and CEO, effective immediately."

Wagoner was asked to step down by the Obama administration as a precondition for the ongoing restructuring within the company.

Wagoner has been CEO since 2000 and has managed the company through some of its most difficult moments.

Over the last four years, GM has reported losses of US$82 billion and nearly ran out of money at the end of last year before the US Treasury Department provided emergency loans.

GM has received US$13.4 billion in loans from the Treasury so far and said in February it needed up to US$16.4 billion in additional aid.

President Barack Obama said in an interview with the Columbia Broadcasting System on Sunday that embattled US automakers had not done enough yet to become "lean, mean and competitive" under federal oversight.

Obama called for "sacrifices from all parties involved -- management, labor, shareholders, creditors, suppliers, dealers." He is expected to announce additional aid for GM and Chrysler LLC on Monday.

US Treasury Secretary Timothy Geithner said on Sunday the government is ready to help Chrysler LLC and GM restructure, but he declined to comment in detail on new steps expected to be announced by the White House on Monday.
