as far we know, he made one comment several years ago.
Living in Glasgow, I work in a very multi cultural environment. I've an Indian worker tell someone else (scottish person) that they were darker than them because they had a good tan, I had a lady from Pakistan tell me her grandson was a half caste and I've had another member of staff use a word (doesn't begin with p) that I felt was totally outdated and possiblly offensive. I asked why she used the word - she said she lost and doesnt know what words you're allowed to use these days plus the African member of staff told her the word was acceptable.
