Three years ago today, the government formally confirmed a moratorium on fracking in England.

DrillOrDrop has compiled this timeline of events that led to the introduction of the 2019 moratorium, its brief lifting and the latest U-turn.

We also look back at an earlier moratorium, introduced in 2011, also prompted by fracking in Lancashire by Cuadrilla. And we give details of moratoriums on fracking in Scotland and Wales, which have remained in force.
