The IPR is now known as the Chartered Institute of Public Relations - CIPR - following Privy Council approval. It now has the same official recognition long since bestowed on professions such as marketing and accountancy.
CIPR director-general Colin Farrington told PRWeek it was now time for people to forget 'old prejudices' about the merits of the PR sector, which, he said had 'passed a milestone' in its development.
He said he wants 'to get to a situation in which the market will demand membership' of the CIPR.
'The most important single thing about this is recognition from the Government,' he added.
The body first approached the Privy Council on the issue in 1951.
