Recycling system in Cambridgeshire that could save thousands of litres a day is deemed not in line with rules

The largest water reuse system in the UK, which could save thousands of litres of water a day for people living in one of the driest regions of the country, is not allowed to be switched on because of drinking water regulations.

As water supplies in England reach critical levels, the Guardian can reveal that a model water recycling system within an urban housing development in Cambridgeshire has not been switched on since it was made ready in 2021.

Amid the grief and rage at a tragic loss, it’s right to differentiate between those who fought a culture war and others who just sought the truth

Even now it is very difficult to process the scale of tragedy that engulfed Jason Arday and those who loved him. The unbearable sadness at his death; the wretched knowledge that the very public onslaught against him began with the malign machinations of a self-defined “race realist” – who believes that, in an ideal world, black people would “disappear from almost all high-profile positions outside of sports and entertainment”. The horror that a rightwing and far-right campaign seeking a victim to fuel its nativist prejudices can now crow that it found one.

There is wide and profound grief and of course there is rage, focused and unfocused. Both were on display as thousands joined a protest vigil in Trafalgar Square on Monday evening.
