Edinburgh-based fund manager Baillie Gifford has revealed it pays its male employees 18% more on average than its female staff per hour, as the deadline for revealing the data approaches.

Last year, Prime Minister Theresa May's government said UK companies with more than 250 staff should publish data each year showing the average pay disparity between men and women. City firms have been slow to reveal their gender pay gap figures ahead of the deadline of April 5.
