The C|T Group founded by Sir Lynton, believes in strategic direction, not just information – and every successful campaign knows which audience will decide the outcome, where they are, what they think and how to communicate with them. It is this understanding of what motivates people that enables us to influence them – persuading by reason, but motivating through emotion. This unique methodology is at the heart of everything the C|T Group does.


Sir Lynton’s intuitive grasp of what it takes to win has been finely honed through years of providing high-level advice to prime ministers, premiers, opposition leaders and leaders of business.
