The welcome but belated recognition by MPs of the terrible injustice done to subpostmasters needs reflection after more urgent issues are addressed (Horizon scandal: hundreds of post office operators to have convictions quashed, 10 January).

Instead, trivial party point-scoring takes precedence over serious scrutiny. Two decades ago, this resulted in Labour boasting of the speed with which it was introducing Horizon.
