Margaret Holt search: Son appeals for missing hiker
The son of a pensioner from Merseyside missing in Lanzarote has appealed on Spanish television for help to find his mother.
Margaret Holt, 65, from Wirral, was last seen leaving her hotel in Costa Teguise on 23 December.
She was spotted later that day in the Orzola region - in the north of the island - but has not been seen since.
Her son Ben said: "One hundred per cent of my focus is on trying to find my mother."
He added: "We need to concentrate on the date on of the 23rd December and concentrate on the northern part of the island."
He urged anyone with any information, no matter how small or seemingly irrelevant it might seem, to contact police.
Mrs Holt, who was described as extremely fit, was last seen wearing a light pink vest, khaki shorts and walking sandals and carrying a drawstring bag.
Her passport and belongings were found in her hotel room, although it is believed she took her mobile phone - which is not working - with her.
A guidebook indicated she planned to walk in the north of the island.
