The main opposition party in Zimbabwe, the Movement for Democratic Change, has said that it will launch a legal challenge today to a last minute change to the country's electoral law decreed by President Robert Mugabe.
With just two days left until the country's Presidential election, voters now have to prove that they live in the constituency where they cast their ballot.
The measure is considered more likely to disqualify urban dwellers who tend to support the Opposition.
The MDC leadership believes that the requirement could cost them tens of thousands of votes.
However the Zimbabwean government has rejected allegations of rigging the election against the MDC candidate, Morgan Tsvangirai.
It says it will deploy 22,000 government employees as election monitors and has pledged that they will act impartially.
