The briefing, tickets for which are on sale, will cover what would-be nominees should include in their awards entry to make it award-winning.
The campaign categories discussion panel includes Dan Neal, co-Founder of Alfred; Elisabeth Field, managing director of Eulogy and Lizzy Pollott, director of Cake.
The second panel, which will discuss the people, consultancy and in-house team of the year categories, includes Bibi Hilton, managing director of Golin and Peter Bowles, co-founder of Dynamo, as well as Shakila Ahmed, comms director at Travelodge.
Both panels will be facilitated by Sheriff, who also chaired last year's stellar judging panel.
The Breakfast Briefing will be on Wednesday, 13 April in London, starting 9am. Tickets are available via the awards website.
