Carol Hawley, defending, said Harper was in the process of selling her £700,000 home to repay some of the stolen cash and was due to exchange contracts. She will be sentenced at a later date. Ms Hawley applied for bail for Harper but Judge Nicholas Loraine-Smith deferred a decision until retiring to consider the matter.
Ms Hawley told the court: "She appreciates the seriousness and has made full admissions in interview. She understands perfectly well on the next occasion she will be facing imprisonment of some length.
"There are some matters to attend to, not least she is in the process of taking steps to repay significant sums of the money that has been taken and has already cashed in her pension and various other shares.
"More significant is her property, on the market - exchange in relation to that property is due to take place today. Completion will be in the period of seven to 10 days. As a result of that she will be able to offer something in the order of £700,000."
