Security officers at the Four Seasons Hotel here in Boston could be forgiven any confusion at arrangements for resident dignitaries. Apart from concerns over the security of the respective teams, there are the visiting police from Cambridge - that's Cambridge, England not Cambridge Massachusetts - who have responsibility for Prince Andrew. Then there is the Spanish security for King Juan Carlos and Queen Sophia.

Meanwhile, there were new arrivals yesterday. US secret service men and state police from Texas and Florida arrived in advance of former US President George Bush and his wife Barbara; Texas Governer and US presidential candidate, George W Bush and his brother, Jeb, the governer of Florida.
