Analysis of Home Office statistics by the Liberal Democrats has shown that Essex's officer numbers rose by only 169 in the last year.
A total of 270 extra officers have been recruited by Essex Police under the Government's campaign that started in September 2019.
Essex Police has so far recruited just 9 more officers per month under the scheme. To meet the Conservatives' own target of 449 by March 2023, that rate would have to increase to 12 per month over the next 15 months.
Essex Liberal Democrats have slammed the government for failing to keep their promise to communities, adding that there needs to be a return to full and proper community policing.
Responding to the figures, Councillor Vicky Davies, Brentwood Liberal Democrat spokesperson for Community, said:
"People in Brentwood and across Essex are being let down and taken for granted by this Conservative Government. With so many local crimes going unsolved, we desperately need more police on our streets and in our communities.
"Liberal Democrats are calling for a return to proper community policing, where officers are visible, trusted and known personally to local people."
"The Conservatives' pledge to boost police officer numbers looks set to become yet another of their broken promises. They are letting down victims of crime and our communities right across our area."
