Polling in parts of Kenya is going into a second day after chaos at polling stations on Monday prevented an unspecified number of people from voting. Millions of people queued patiently for hours after ballot boxes failed to arrive or were sent to the wrong place. The electoral commission blamed logistical problems. In constituencies where voting was completed, counting was delayed until this morning. Our East Africa correspondent, Cathy Jenkins, reports:

At Nairobi city hall, dozens of party agents, candidates and electoral officials had sat up all night keeping vigil over ballot boxes instead of counting the ballot papers inside them.

There had been initial confusion after the electoral commission announced that counting would not start until this morning.

But the general opinion was that the boxes had been well watched and problems had been minimal.

But tension in the city hall was just below the surface as people began to demand that the counting process get under way.

The electoral commission said counting in those constituencies where polling was completed should start no later than eight o'clock. But in City Hall the start of the process still seems some way off.

After Monday's chaos, the electoral commission announced that polling would take place on Tuesday in areas where the exercise had failed.

It did not specify how many polling stations were involved. The commission said the confusion was due to logistical problems and severe weather conditions in some areas.

Opposition leaders immediately accused the government of trying to undermine the fairness of the poll.
