Laura Plummer, 33, was arrested on October 9 at Hurghada Airport for possessing 290 pills of Tramadol, a pain-relieving drug which is illegal in Egypt but not in the UK. Tramadol is legal in the United Kingdom with a prescription, but illegal in Egypt.
Despite that, Plummer's family claim that Omar Caboo, Laura's former husband, had previously presented to them evidence that he suffered from long-term back problems.
The black market for Tramadol has grown in Egypt over the past decade, with many using the drug recreationally as a heroin substitute.
"It clearly is a banned substance and whilst we must respect the law of other countries there must be good sense and fair play as well". "She doesn't deserve that".
The trial of British citizen Laura Plummer has been postponed to Boxing Day after confusion in the courtroom caused her to unintentionally plead guilty to charges of drug trafficking.
Laura's mum, Roberta Sinclair, says her daughter made no attempt to hide the medicine and thought it was a joke when she was first pulled over by officials.
The case was adjourned until Tuesday when her lawyer are expected to begin her defence and submit documents showing Omar Abdel Azim and his mother are being treated for illnesses that need Tramadol.More news: Firefighter's family loses home and Christmas gifts in house fire

In an interview with the British newspaper the Guardian, Rachel Plummer - Laura's sister - expressed her shock at the final verdict.
Plummer told authorities that the painkillers were for her partner's bad back; the two had planned a holiday in the resort town of Hurghada on the Red Sea. Instead, she was placed in a cell with 25 other women for almost a month.
Her lawyer Mohamed Othman said a plane ticket which showed she paid twice as much for her flights as the drugs were worth shows she was not looking to sell them.
Her other sister Jayne Synclair said Plummer had only been trying to help her partner.
"Her father said to me "look, the truth is she wouldn't know tramadol from a panadol".
"I am hopeful that good sense will eventually prevail", he told BBC Radio 4's The World At One. She's out there by herself.
