Pope Benedict and the Archbishop of Canterbury discussed Christian-Muslim relations yesterday in their first meeting since the Anglican leader caused a storm with comments on the role of Sharia law in Britain.

The Vatican said the Pope had received Rowan Williams in a private audience but gave no details.

An Anglican spokesman said the two spoke privately for about 20 minutes and discussed Christian-Muslim relations, inter-faith dialogue and the Pope's impression of his visit to the US last month.

He described the visit, the second official meeting between the Pope and the spiritual leader of the world's 77 million Anglicans, as "warm and friendly".

In March Cardinal Jean-Louis Tauran, the Vatican's top man for relations with Islam, criticised Archbishop Williams as mistaken and "naïve" for suggesting that it was unavoidable that some aspects of Sharia, Islamic law, would be adopted in Britain.

Archbishop Williams's remarks, in a speech in February, sparked a storm in Britain and beyond and became part of a broader debate on how to integrate Britain's 1.8 million Muslims.

He is in Rome for the Seventh Building Bridges Seminar, an annual meeting of leading Christian and Muslim scholars for intensive study of Biblical and Koranic texts.

Relations between the Catholic and Anglican Churches have been strained over the past decade over the issue of women priests and homosexual bishops in the Anglican Church, which both leaders have acknowledged as obstacles to unity.
