THE disappearance of Alexandria mum Lisa Brown has been broadcast in a new documentary shown on Spanish TV.

The 32-year-old mum of one was reported missing by former partner on November 4, 2015, after failing to collect their son from school in Andalucia, near to its border with Gibraltar.

The mystery of what happened to Lisa has been kept in the spotlight by her family and her disappearance was even raised during Prime Minister’s Question Time in Westminster.

At the time Martin Docherty-Hughes MP raised the matter with then PM David Cameron.

Liverpool man Simon Corner, who Lisa was involved in a relationship with, could hold the key to what happened to her.

Corner disappeared from the area shortly after giving a statement to police and later commented through a legal representative that he could not help any further with the investigation.

Corner initially ignored pleas from Lisa’s family and friends to return to Spain and help with further enquiries into her disappearance.

Since then, however, he was held in custody on suspicion of killing Lisa since being detained in Denmark last year, then extradited to Spain.

He is now understood to be out on bail.

Now Spanish TV channel La Sexta has aired a documentary about the case and now the sister of missing Lisa has vowed to find the truth behind her disappearance.

Helen Jordan, 50, added that the family will never quit in their attempts to find out what has happened.

Speaking in the wake of the documentary Helen said: "Many thanks to the Spanish TV La Sexta for the well documented story on Lisa's disappearance.

"We are extremely grateful to them for keeping Lisa in the public eye."

In February, The Reporter told how the search to find missing Lisa took a new twist after detectives called in diggers to search near her home in Spain.

It’s understood that the operation was prompted by a tip-off.

Police had hoped the information they received could shed further light on Lisa’s disappearance back in November 2015.

A group of Civil Guards, along with mechanical diggers, took part in the operation in Guadiaro, on the Costa del Sol.

Some items uncovered were passed on to forensic experts but the relevance or otherwise has not been revealed.

In 2016 Lisa's family put up a reward of £6,500 for information leading to her discovery.

The 32-year-old mum of one is a former Our Lady and St Patrick’s High School pupil.

Meanwhile, family members and friends of missing Lisa Brown will climb Ben Lomond in her honour.

Helen said: "We Lisa's family, along with friends, are climbing Ben Lomond on Saturday 15th July as a fundraising event and every penny raised will be put towards a reward for information leading to the whereabouts of Lisa.

"Anyone wishing to join us on this day either to fundraise or just for support will be warmly welcomed.

"Please contact the page via messenger for details of sponsor forms, how to donate and times."

She added: "Thank you everyone for your continued support it is hugely appreciated.

"Sadly this is the lengths we are having to go to but for our girl we will do anything."
