The full statement from Cardinal Keith O'Brien:
In recent days certain allegations which have been made against me have
become public. Initially, their anonymous and non-specific nature led me
to contest them.
However, I wish to take this opportunity to admit that there have been
times that my sexual conduct has fallen below the standards expected of me
as a priest, archbishop and cardinal.
To those I have offended, I apologise and ask forgiveness.
To the Catholic Church and people of Scotland, I also apologise.
I will now spend the rest of my life in retirement. I will play no further
part in the public life of the Catholic Church in Scotland.
