Pope Benedict arrives in Britain
The Pope was officially welcomed by Queen Elizabeth with a ceremony full of pageantry at the start of a tour meant to strengthen ties with the UK's six million Catholics and the wider nation.
The highlight of the visit for Catholics will be the Pope's beatification of Cardinal John Henry Newman - the 19th century cleric who converted from the Church of England.
But the trip comes amid renewed anger at the worldwide child abuse scandal that has engulfed the Roman Catholic Church and dogged the Pope's own religious career.
That anger has gathered pace with recent revelations in Belgium of hundreds of new victims, at least 13 of whom committed suicide over the years.
Victims abused by priests, and secular campaigners, have called on the pontiff to go further than an apology and hand over all information about suspected abusers within the church.
In his comments on board his plane, the Pope said abusive priests must never have access to children, saying they suffered from an illness that mere "goodwill" could not cure.
The Pope is widely expected to meet some of those who suffered during his visit to Britain.
In another development, German-born Cardinal Walter Kasper, 77, withdrew from the Pope's entourage after suggesting Britain was like a "Third World country" with its multi-cultural population.
Vatican officials attributed the change of plans to ill health and distanced the Church from the comments.
But the Cardinal was under growing pressure to apologise for his comments.
It is the first papal trip to Britain since Pope John Paul II made a pastoral visit in 1982 following an invitation from the Church.
Thousand lined the streets as the Pope was driven through Edinburgh, and past the controversial Scottish Parliament building, to the Palace of Holyroodhouse for his meeting with the Queen.
