ONE of the directors of Scotland's largest public relations agency has stepped down after more than 12 years with the business.

However Marjorie Calder will continue working for BIG Partnership on a consultancy basis.

Her resignation was noted in a filing at Companies House.

Ms Calder, who joined BIG in 2003 and was made a director three years later, said she was looking forward to her "new adventure" and intends to take the rest of the summer off before deciding what to do next.

She said: "It just felt like the right time to have a change."

BIG Partnership co-founder Alex Barr described the parting as "most amicable".

Mr Barr confirmed Ms Calder will still be offering media training for clients of the company.

He added: "She has been a fantastic contributor to the growth of the business over the past 13 years and is definitely one of our best ever signings."

In February this year Andrew Baird, Bryan Garvie and Sharon Mars were promoted to BIG's board as directors.

At the same time it announced a 12 per cent lift in pre-tax profits from £1.05 million to £1.18m.

That came on the back of a rise in turnover from £7.1m to £7.8m in the 12 months to the end of May 2014.

BIG, which has been ranked the largest public relations agency outside of London for the past seven years, has offices in Glasgow, Edinburgh, Dunfermline, Aberdeen and Liverpool.
