Due to a clerical error, we stated that responses to this FOI request were not received from Havering and the City of London. In fact, responses were indeed received from them and they have now been included in the revised report, available here.
A clarification has also been posted with respect of Glasgow City Council and late-responding councils have been included too.
We apologise to those councils for wrongly "naming and shaming" them.
The inclusion of their expenditure raises the total amount spent on CCTV in the past three years by councils in the UK to £321,331,453.18.
