He or she is not yet on the agenda, but here’s how you can try to work out who it is and win a #FOM15 ticket to boot…

How to play

Beginning at 10am tomorrow morning (Thursday 8 October) we will post clues to the speaker’s identity from the Festival of Marketing Twitter feed.

To give you a headstart, this person comes from the world of celebrity rather than being a brand marketer.

There will be four clues throughout the day, each alluding to one of the speaker’s achievements or something they’re well known for.

Once you think you know who the speaker is you need to tweet their name, followed by the Festival of Marketing Twitter handle (@FestofMarketing) and the hashtag #FOMCOMP.

As an example, your entry might look like this (but please note that I am not the secret speaker, sorry to disappoint you all):

David Moth @FestofMarketing #FOMCOMP

The competition closes at 5pm GMT so make sure to have your guesses in by then. 

You can guess more than once, but obviously if you get it right you will only be entered into the prize draw once. The winner will be announced on Monday 12 October on Twitter.

Entrants must be 18 or over and resident in the UK, and you can read all the small print here.

So, good luck everyone and make sure to follow @FestofMarketing for the clues on Thursday 8 October. 

And if you aren’t lucky this time round, fear not as we’ll be doing similar ticket giveaways via Twitter for the next few weeks.
