Baby dies at South Australian polling booth

A teddy bear and flowers have been laid in memory of a baby boy who died while his mother handed out how to vote cards for a Greens candidate in South Australia.

The mother was handing out how to vote cards for Finniss candidate Moira Jenkins at the Middleton polling booth about 10am when the child became ill.

He was rushed to the Flinders Medical Centre where he later died in hospital.

Greens candidate Moira Jenkins said she was devastated by the loss.

"It's an absolute tragedy, our thoughts are with the family," she said.

Moira described the mother and baby as great supporters and friends.

"It's been a tragic day."

Ms Jenkins cancelled plans for an election party. She spent the remainder of Saturday counselling volunteers at other election booths. 

Friends of the volunteer's family placed a tribute of flowers and a teddy bear at polling booth at the Middleton hall which remained open after the incident.
