How many convictions do prisoners serving under three years have?

I asked Corrections how many convictions prisoners serving a sentence of under three years have.

Many might assume that the vast majority are first time offenders.

In fact only 23% have 10 or fewer convictions.

A massive 46% have 25 or more convictions.

17% have 50 or more convictions.

And 3% have 100 or more convictions.

These are who Labour wants to grant the vote to.
