– Gerald Davies
I have always believed and stated that as rugby changes so its organisation must also change anD develop for the common good of all.
I do not wish to sever my ties completely with rugby and will constantly look for opportunities to encourage and support the game that is so dear to my heart.
I will watch with interest how the WRU meets the many challenges ahead."
