Election laws exist to protect our democracy and ensure a level playing field. Candidates and parties must declare all their campaign spending, and stick within spending limits, to stop richer parties gaining an unfair advantage.
Yet a Channel 4 investigation has uncovered compelling evidence suggesting large-scale and systematic abuse of election rules by the Conservative Party in last year's General Election and three key by-elections in 2014.
The alleged abuse strikes at the very heart of fairness in Britain and the integrity of our democracy. Now the Electoral Commission has launched an investigation, along with ten police forces across the country.
