Labour is setting up an expert commission tasked with drawing up reforms to increase the number of crimes solved.
The Charging Commission will propose ways to help police and prosecutors bring more criminals to justice.Home Office data show 2.4 million cases were dropped over evidential difficulties in the year ending March 2023.
The government said it was determined to bring all offenders to justice.
But shadow home secretary Yvette Cooper said the Conservative government’s record on law and order was one of “damaging decline and collapsing confidence in the criminal justice system”.
Ms Cooper said Labour’s expert commission would help “turn things around” and “deliver on our pledge to make Britain safer”.
