Late cancellation may be sign Queen’s busy schedule is taking a toll

Analysis: 95-year-old monarch has been to Wales and Ascot in the last week and has key events coming up

The Queen's 11th-hour cancellation for medical reasons of a long-planned visit to Northern Ireland comes at a busy period for the 95-year-old monarch, and is a decision that will not have been taken lightly.

Much preparation goes into official visits. On this occasion the Queen was due to meet members of the community at Hillsborough and attend a service of reconciliation and hope at St Patrick's Cathedral in Armagh, marking the centenary of partition and Northern Ireland's foundation, alongside Boris Johnson.
