Ambrozine Heron, 77, and her daughter Paulette Chambers, 49, were intercepted by customs officials at Dover after they had made a total of 14 trips to Holland.

A search revealed 40 tins labelled as palm oil that contained cocaine.

“I don’t know anything about that," said Heron when questioned by officials.

“I just went with my daughter."

"I didn’t ask any questions because I’m not a nosy person."

“I don’t smoke or drink."

"What am I doing with drugs?”

Although Heron denied her involvement, her daughter admitted her role in the smuggling operation.

Edmund Anderson, a 47-year-old security guard indicted in the case was acquitted of any involvement.

He originally told customs officers that he had been on holiday in the south of France with the two women -- but he claimed later that he was merely acting as a taxi driver for them.

Heron claimed that Chambers was having an affair with her daughter -- a claim he denied.

Chambers told Canterbury Crown Court that he did not know what was happening when he dropped the two women off at an apartment building in Amsterdam.

The grandmother now faces a lengthy prison sentence after being found guilty of importing Class A drugs.

Although she suffers from asthma, diabetes and arthritis, the severity of the crime means that a custodial sentence is almost certain -- especially as she denied her involvement.
