Scotland's Power100 - 81-90

81 Donald Shaw

The celebrated musician, producer and composer is popular as one of the co-founders of Capercaillie, but his influence on music, particularly live music, extends around the world.

As artistic director for Glasgow's Celtic Connections festival, the 47-year-old has massively expanded the event and has looked overseas for new potential.

Recently he announced the festival is exploring a plan for a satellite festival in New York.

Watch out for: Next year's Celtic Connections becoming even bigger. It will feature 2,000 musicians in 300 shows.

82 Sir Brian Souter

The son of a bus driver and a former conductor who became chairman and chief executive of Stagecoach, Sir Brian has often sought to exert political ­influence, sometimes controversially.

In 2000, he funded the Keep the Clause campaign to maintain anti-gay legislation in Scotland, and was one of the million-pound backers of the Yes campaign.

He also runs a charitable trust which he set up with his wife Betty, which supports causes in the UK and abroad.

Greatest achievement: Building Stagecoach into one of the UK's leading bus and rail companies.

83 Jackie Killeen

As the Scotland director for the Big Lottery Fund for the last three years and the woman with responsibility for distributing money to charities across the country, Killeen, 33, has the potential to influence thousands of lives for the better.

In what is arguably the most powerful job in the voluntary sector, she also engages with the Scottish Government and develops the Big Lottery's fund policy.

Watch out for: The fund's stated priorities for the years after 2015 when the current funding plans end.

84 Larry Flanagan

As general secretary of the Educational Institute of Scotland (EIS), 51-year-old Flanagan has profound influence over the working lives of teachers and the school lives of children.

Partly this is because the EIS is Scotland's largest teaching union and has the power, if it should want to, to shut schools down, but partly it is because Flanagan plays a pivotal role in the development of educational policy.  Many of the tweaks and changes made to Curriculum for Excellence came from him.

Greatest achievement: The former teacher is a strong defender of comprehensive education, having worked in the system his whole career.

85 Alasdair Gray

A writer and artist since boyhood, Gray studied at the Glasgow School of Art, yet made his name - and Glasgow's - with his fantastical novel Lanark in 1981.

Subsequent works, such as Poor Things and Something Leather confirmed his position as a literary one-off, but eschewing fame or fortune, he refused to be tamed by success, and remains as outspoken and original a thinker as he always was.

His fingerprints are all over the city, in his distinctive murals, on the underground, and elsewhere.

Watch out for: Anything - he is impossible to predict.

86 Professor Pamela Gillies

In a sector that is critical to Scotland's economic success, Pamela Gillies is one of the most important figures.

Earlier this year, it was revealed the 57-year-old principal and vice-chancellor of Glasgow Caledonian University was one of only two university leaders in Scotland not to take a pay rise, marking her as out as politically astute.

She also has new ideas: GCU was the first Scottish University to have a campus in London and last year became the first British university to have one in New York.

Watch out for: Another campus in another place.

87 Jamie Byng

Publisher of Canongate books, who turned this bijou Scottish company devoted mainly to classics into one of the most innovative and successful publishers in Britain, and beyond. Byng, the second son of the eighth Earl of Strafford, started on work placement and swiftly rose to fame by buying the company and changing its direction.

An early triumph with Yann Martel's Booker-winning novel The Life of Pi bolstered Canongate's bank balance as well as its reputation, since when it has flourished as a canny, forward-looking firm that brings a touch of glamour to Scottish publishing.

Greatest achievement: Publishing Barack Obama's autobiographies.

88  Lesley Riddoch

After many years of experience on television and radio with the BBC and Channel 4, the referendum campaign saw Riddoch emerge as one of the strongest and most strident voices for independence.

She uses her newspaper columns to explain her views, and produces feisty, frothy podcasts from her base in Dundee. She is also founder and director of Nordic Horizons, a group that brings Nordic experts to Scotland to meet policy makers.

Watch out for: The possibility of Riddoch standing for election. Her name has been mentioned as one of the prominent Yes campaigners who may fight a seat next year.

89 Richard Lochhead

His wide-ranging portfolio means the Cabinet Secretary for Rural Affairs, Food and the Environment is responsible for progressing the new EU Common Agricultural Policy, defending the Scottish fishing industry (which represents two-thirds of the UK industry) in Brussels.

He is also continuing his stewardship of the 2009 Food and Drink Policy for Scotland through its next phase, Becoming A Good Food Nation, aimed at improving the nation's dietary habits. After a recent public consultation this will be implemented during the 2015 Year of Food and Drink.

Most likely to say: "Please, Miss, may I have a deputy?"

90 Joanna Blythman

The food campaigner and journalist, and sometimes excoriating restaurant reviewer of The Sunday Herald, was born in Springburn in Glasgow's East End, the daughter of the late socialist campaigner and republican songwriter Morris Blythman, so questioning the British food culture is in her DNA.

Blythman has authored seminal titles Shopped: The Shocking Power of the Supermarkets, Bad Food Britain, and How to Avoid GM Food. Swallow This, a look at the processed food industry, is published in February.

Least likely to say: "Oh, goodie, there's a BOGOF offer at Tesco!"
