Ande Macpherson, regional content director for Bauer City North West, has resigned from his role with immediate effect.
Macpherson had taken the job, which saw him handling content teams at Key 103, Radio City and Rock FM, in 2013 after previously working for More FM in New Zealand.
No reason has been given for his departure.
His role will be taken by Mike Cass, in addition to his work as regional content director for Bauer City 2 and 3.
Recruitment for a regional content director for Bauer City Yorkshire will begin this week.
Owen Ryan, group content director for Bauer City Network, said: “We are grateful to Ande for his work and leadership across the region over the last 18 months and wish him all the best for the future.”
