On his appointment as Her Majesty’s Ambassador to the Holy See, Mr Baker has said:
"I am delighted and honoured to be taking up this posting. The last few years have seen the development of a strong and fruitful global partnership between the United Kingdom and the Holy See.
"The historic visit of Pope Benedict XVI in September 2010 reinforced that relationship and opened new avenues for bilateral and multilateral collaboration. I look forward to the challenge of deepening our engagement across the many issues on which we work together."
