Labour's soft justice programme has been left in tatters after watchdogs warned the public are being put at risk by major problems with electronic tagging.One in seven criminals ordered to take part in electronic monitoring schemes never even get a tag fitted. Labour is introducing controversial measures to slash the number of criminals who are sent to jail, placing a huge emphasis on community punishments backed up by tagging.But the National Audit Office (NAO) highlighted concerns over whether tagging can be 'safely scaled up' to replace jail sentences.The Ministry of Justice (MoJ) is spending 175million to expand tagging operations run by the HM Prisons and Probation Service (HMPPS) over the next three years.But the NAO report said: 'HMPPS is continuing to scale the service while key elements are not yet working effectively, leading the service to operate beyond its stated risk appetite and tolerance levels.'This increases the risk of poor performance and threats to public protection escalating as demand grows.'The watchdog found nearly 9,000 criminals – amounting to a quarter of those ordered to wear a tag by the courts or after being released from jail – had not been fitted with the devices at the end of March.
