JAILED drug mule Melissa Reid is still waiting on the go-ahead for her proposed transfer back to Scotland, with reports that it could still be overturned by Peru's president.

Reid, who is from Lenzie near Glasgow, was sentenced to six years and eight months in prison after smuggling cocaine worth £1.5million through Lima airport in 2013..

The 22-year-old was jailed alongside Michaella McCollum, 21, in a high-profile case which saw the friends nicknamed the 'Peru Two'.

The Scottish Prison Service have agreed for Reid being transferred to a Scottish prison last August, however the process has been hit by numerous delays.

A Sunday publication has reported that court insiders say Peru's president, Ollanta Humala, has the final word on the transfer and could still deny her request.

A source in the Peruvian justice system reportedly said: "The final stage of the transfer after the court approves it is that President Humala signs it off.

"The president’s signature is entirely at his own discretion. He is under no obligation to sign off the transfer.

"Reid’s return to the UK is not a formality and shouldn’t be treated as such.

"Drugs are a controversial issue in Peru and Humala vowed to fight against them when he was elected."

Yesterday, a spokesman for the Scottish Prison Service said: “We cannot comment on individual cases.”

Magaly Cigarrostegui, from the president’s office, reportedly said: "If the judicial authorities send it here, we’ll take a look at it.

"But we can’t comment now about something that has yet to happen."
