Zimbabwean President Robert Mugabe's main rival Morgan Tsvangirai has withdrawn a legal challenge against the outcome of last month's disputed election, his MDC party has said.

"The prime minister has withdrawn his election petition," Movement for Democratic Change spokesman Douglas Mwonzora said on Friday.

He said the challenge was withdrawn as it was felt the legal process would not be fair.

Tsvangirai had mounted the challenge after alleging widespread fraud in the presidential and parliamentary elections that Mugabe and his ruling Zanu-PF party won with a landslide.

Mugabe, who has led the country since its independence in 1980, has rubbished the fraud claims.
