Hundreds of thousands of people are expected to gather in London, with leaders from across the globe flying in to pay their respects.

When and where is the funeral taking place?
The state funeral service will begin at 6 a.m. ET (11 am UK time) on Monday and run for an hour.

After the prayers, the sermon and commendation will be given by Archbishop of Canterbury.
A two-minute silence will be observed in the Abbey and across the country, followed by the national anthem to bring the funeral service to a close at 7 a.m. ET.
London’s Heathrow Airport announced it will halt all flights for 15 minutes before the two-minute national silence.
According to Edward William Fitzalan-Howard, the official in charge of arrangements, the funeral and memorial events are intended to “unite people across the globe and resonate with people of all faiths, whilst fulfilling her majesty and family’s wishes to pay a fitting tribute to an extraordinary reign.”
