A drive to more than double the turnover of Scotland's food and drink sector has been unveiled.

Scotland Food and Drink says the sector is worth £14.4 billion annually and employs 119,000 people directly in food manufacturing.

The Ambition 2030 strategy unveiled on Thursday hopes to increase turnover of the farming, fishing, food and drink industries to £30 billion by 2030.

Food and drink experts say it is Scotland's best-performing sector and is growing at twice the rate of the UK average.

Scotland Food and Drink chief executive James Withers said: "Ten years ago, when the Scotland Food and Drink partnership was formed, our sector was relatively static.

"It is now one of the country's best-performing industries and it's our fastest-growing export sector. However, today sets out a new vision to build further on that.

"As an industry, we have identified an opportunity to more than double the size of our sector to £30 billion by 2030, making it Scotland's most valuable industry.

"A huge amount of work is required to unlock that potential and it will not come easily.

"There is uncertainty ahead, with Brexit in the forefront of everybody's mind.

"Whilst big political upheavals are out of the industry's control, we can control how we develop the Scottish brand, the markets we want to sell to and the investments we make in improving skills, innovation and supply chains."

The strategy, launched by First Minister Nicola Sturgeon, has been developed by the Scotland Food and Drink partnership with representatives from farming, fishing, food and drink sectors.

It will focus on building Scotland's national brand as a land of food and drink and driving sales in Scotland, the UK and globally.

The plan also hopes to raise the attractiveness of the industry as a career and ensure farmers, fishermen, manufacturers and buyers share in profitability.

Scotch Whisky Association acting chief executive Julie Hesketh-Laird said: "Scottish food and drink is of significant importance to the country's economic and export performance, with Scotch whisky playing a leading role in growing the industry further.

"The new strategy, Ambition 2030, will ensure that the whole sector will become even more substantial in years to come."
