Scottish local and parliamentary elections results have been delayed and questioned due to chaos caused by another new computerised system.

Widespread reports of ‘technical glitches’ with a computerised vote counting system used live for the first time last night have delayed results in at least nine constituencies, while the high number of votes excluded have also been questioned.

New MSP for the Gordon constituency, SNP leader Alex Salmond criticised the voting arrangements and also earlier problems with postal voting in his victory speech. “Postal voting arrangements for this election across Scotland were totally inadequate,” he said. “Tens of thousands of votes across Scotland have been discounted. That is totally unacceptable in a democratic society."

The system, supplied by automated data capture specialist DRS, was bought by the Scottish Parliament last year and went through successful testing before yesterday’s elections. It also follows successful use of similar systems in 2001 when the capital’s voters went to the polls for the London Assembly.

Computerworld UK reports that, while a Scotland government spokesman said technical issues had disrupted vote counting, the Electoral Commission has said it will undertake a full review of the disruption to last night’s procedures.
