The PR agency behind Peter Casey's Presidential bid has apologised for re-tweeting a video which satirised the businessman's Late Late show appearance and his views on the traveling community.

Bannerton PR has since deleted the tweet, and "apologised wholeheartedly" to anyone who may have been offended by the clip.

It features a cartoon of Ryan Tubridy interviewing Mr. Casey, with audio from Joe Joyce interjected into it.

However, the company says it doesn't support the content of the video in any way, and shouldn't be linked to any of its employees.

Bannerton PR has also said it is not longer managing Mr. Casey's public relations and cannot comment on his behalf.

The video itself, was also retweeted by Peter Casey himself, and tagged the PR company in his tweet.

Mr. Casey has deleted the tweet this afternoon.
