"When hard working Metropolitan Police officers were confronted with the reality that their Big Brother Bosses were secretly monitoring their movements it caused a lot of sleepless nights and anxiety.
"Everyone will agree that the very small number of bad police officers who are not fit to serve should not be in the police service. There are processes in place to deal with these people.
"We have made very clear our concerns around this unchecked use of a controversial AI provider to spy on every single one of our colleagues. This was not proportionate, just or proper.
"The Federation welcomes this decisive intervention of the Mayor's office. The use of AI to spy on our members is unacceptable - police officers do not deserve to be treated and indeed tarnished with this level of suspicion.
"We fear it will take some time for the Chief Officers in the Metropolitan Police to rebuild trust amongst our courageous rank and file cops."
