Background
To stop injustice of political party (A) being allowed to increase influence by poaching constituencies won by party (B). In such cases voters are left feeling deceived, and their voices, muted. The change in law would help improve voter confidence, and encourage increased voter turnout out, which has been getting progressively worse. 2019 average turnout all regions (England, Wales, NI) 66.7% turnout. 2024 59.1%
