A Metropolitan Police spokesperson told us: “It is always challenging to estimate crowd numbers at protests and it is not unusual for there to be significant differences between police and organiser estimates. We use a combination of drone, helicopter and CCTV footage, alongside crowd density estimates, to calculate likely numbers.
To provide well-rounded coverage and a breadth of insight across various events, we rely on contributions from several staff writers, each bringing their own area of expertise to our publication.
