"In the current economic climate it has never been more important to ensure you keep ahead of the changes in the industry and be in a position to respond to them," said Confex event director Duncan Reid.
"Confex Knowledge can give you the inspiration to do this and I expect to see even more visitors look to take advantage of the free seminar content this year."
Hamish McRae is the principal economic commentator for The Independent, Ruby Wax is a well known face from TV, stage and radio, and Kelvin MacKenzie is the former editor of The Sun.
There will also be 55 free seminars over the three day show including a session with Kristina Grimes and Jennifer Celerier, former finalists of BBC show The Apprentice.
The show takes place at Earl's Court from 24-26 February.
