The events will be held at some of the PRWeek UK Top 150 agencies - although the host agency will be kept a secret - giving attendees the chance to have a glimpse inside a competitor's workspace.
Teasers will be sent out via social media prior to each event. Panels will include a mix of senior agency and in-house senior professionals working with some of the biggest and most exciting brands.
As well as free drinks and networking, there will be the opportunity to put questions to the panel, get tips and advice, and find out how to further your career in PR.
The first #SecretTop150 will take place on Wednesday 28 October. Details will be released nearer the time, with a limited number of tickets which can be purchased here.
