Yelland’s 20-year journalism career includes 14 years at News Corporation and five years as editor of The Sun.
Yelland said: ‘I do not regard this as a way of finishing my career, I see it as being half-way; I am 41.
‘Too many journalists are going into PR because they think it is an easy way out, but I know it is a profession that is very different from journalism and I know I have got a severe learning curve,’ he added.
In the newly created role, Yelland will work in media relations, business development and strategy. Byrne said: ‘David will take an external-facing role, which is something that we have not had since [Lord] Chadlington sold the business and took a back seat.’
