President Robert Mugabe, the only leader independent Zimbabwe has ever known, resigned Tuesday after nearly a week under house arrest. Mugabe had faced intense pressure to step down from the military, from his former deputy and from powerful war veterans, and from growing numbers of ordinary Zimbabweans.

Correspondent Sebastian Mhofu reports from the capital, Harare.

After a week of house arrest, negotiations, loud protests and finally impeachment proceedings, Robert Mugabe's epic 37-year tenure as Zimbabwe's head of state has ended.

Speaker Jacob Mudenda read Mugabe's resignation letter just after parliament had moved to bigger facilities to begin impeachment proceedings.

With words "I, Robert Gabriel Mugabe, in terms of Section 96 of the Constitution of Zimbabwe, hereby formally tender my resignation with immediate effect."

The house erupted into cheers, which spread to its cheers of Harare, the capital.
