HARARE, June 1 (Reuters) - President Robert Mugabe has left Zimbabwe to attend a food summit in Rome in his first visit to the West since March 29 parliamentary elections which his ruling party lost to the opposition, state television said on Sunday.

Mugabe travelled accompanied by his wife and several senior government officials, state television said without giving more details.

Western powers accuse Mugabe, who has ruled Zimbabwe since independence in 1980, of wrecking the once-prosperous country and of using violence against his opponents. He faces a June 27 presidential run-off against opposition leader Morgan Tsvangirai.
