A Perth woman who was to face trial accused of stealing more than $110,000 from an elderly friend has lodged a last-minute plea of guilty.

Yvonne Joan Rollans, 58, was charged with 102 stealing offences after she used the credit card of a 95-year-old woman she was caring for to buy items for herself and her family between 2009 and 2011.

Rollans’ trial was due to begin on Monday but she pleaded guilty.

She is scheduled to be sentenced next month.
