We have received the following message from the ECB, linking to videos which explain the law changes to cricket that came into place last October and how they apply to adult levels of cricket that have official umpires, players taking turns umpiring and revisions to junior regulations, too.
Please watch the video and see the new laws for no balls - which has changed to allowing only one bounce only before the popping crease - and other changes. There is also an online tool to explain "unfair play" and "player conduct" laws.
