"Pope Benedict XVI has been officially welcomed by the Queen as he arrived in Britain for his historic state visit. He was formally greeted by the monarch in a ceremony full of pomp and pageantry in the shadow of Edinburgh's Palace of Holyrood House. The Queen and the Pope, both heads of state, shook hands for a few moments as the Pontiff began a four-day tour which will include Masses and meetings in Edinburgh, Glasgow, London and Birmingham. The Pope had travelled the short distance from Edinburgh Airport, where his plane landed, and looked relaxed as he stepped from a limousine which swept into the Palace's courtyard in a motorcade. Thousands of onlookers watched the cars speed through the streets of central Edinburgh for the meeting at the Queen's official home in Scotland."
