Papal visit: Pope to begin historic UK trip
The first state visit by a Pope to the UK gets under way later when Benedict XVI flies into Edinburgh.
He will meet the Queen at Holyrood House and parade through the city before an open-air Mass in Glasgow.
Tens of thousands of people are expected to line the streets to catch a glimpse of the Roman Catholic leader.
Some ticketed events during the four-day trip have not sold out and protests are planned over Vatican policies on birth control, gay rights and abortion.
The visit is the first to the UK by a Pontiff since John Paul II in 1982.
