Around 260 jobs are set to be lost after electronics firm Jabil announced plans to close its plant in Livingston.

The Florida-based multinational said the move followed a review which found there was "unsustainable demand" to continue manufacturing at the West Lothian site.

A consultation with staff is under way. Around 100 "support-based employees" are expected to be retained at the site.

The announcement comes just weeks after Johnson & Johnson announced it was closing its Livingston plant with the loss of 400 jobs.

A statement from Jabil said: "Following a detailed strategic review of the Jabil Livingston site business plan and future loading requirements, we have concluded that there is unsustainable current and future demand to support the viability of the site.

"After careful consideration of all viable options, we are today announcing the commencement of a formal consultation process with our employees, with the intention of a phased run-down of manufacturing at the site.

"It is anticipated that manufacturing will cease by the end of calendar year 2017."

It continued: "This announcement is in no way a reflection of the hard work, dedication and loyalty of our Livingston-based employees.

"We are committed to supporting them throughout the consultation process and subsequent career search."

A Jabil plant based at Ayr will not be affected.

West Lothian Council has pledged to support workers.

A spokeswoman said: "News that the plant is to close is extremely disappointing and our immediate thoughts are with those staff affected and their families.

"Jabil is well established and a significant employer in the area. This closure comes only a matter of weeks after the announcement that Johnston and Johnston are to close their Livingston plant with the loss of approximately 400 jobs.

"We will seek to meet with the Jabil's senior management and our partners as quickly as possible to discuss all and any alternatives to safeguard these jobs. We are keen to meet with the company's representatives so that we can understand the decision that they have made.

"We will do all we can to ensure that all options are explored, and support and contribute to any plans that would help safeguard jobs."

She added: "Livingston has a strong economy and West Lothian's unemployment rate is below the Scottish average, but there is no doubt that these closures will adversely affect the local area and will impact upon local people.

"Removing approximately 700 jobs from the local economy would be devastating for any area in Scotland.

"There is a clear need for a quick and robust response to these closures and we are calling on all stakeholders, including the Scottish Government, Scottish Enterprise, SDI, Skills Development Scotland, to work together to deliver a solution which helps to protect vital local jobs in West Lothian going forward."
