Radio host Michael Savage has said he is suing for defamation after the Home Office placed him on the list of people banned from entering the UK.
He has called in PHA Media as he continues to rail against the ban.
Senior consultant Phil Taylor said: 'This is about him wanting to get across how disgusted he is. We will be keeping the campaign going in the media on a daily basis.'
Savage is the latest controversial client for PHA, run by former News of the World editor Phil Hall. Already this year the agency has been hired by detested banker Fred Goodwin and under-fire chef Gordon Ramsay.
