Computerised tabulation of votes in the just-ended Mozambican presidential and parliamentary elections failed to start as planned on Wednesday due to technical problems, an electoral official said on Thursday. Tabulation of provincial results will only begin later on Thursday. Physical counting of votes at the polling stations started immediately after polling ended on Sunday. The counted ballots were then to be fed into computers operating on two separate networks handling the same data to minimise the possibility of error. Members of the public would be able to consult the data in the system. Provincial results are expected to be published by Sunday while final definitive national results will not be availiable until December 19. However, these legal deadlines might be affected by the one-day extension of polling. Voting had to be extended by a day after some polling stations failed to open on time due to bad weather.
