 This increased the population of the borough to 12,818, although only 869 of these were eligible to vote in the first election after Reform; this had grown to just over 1,000 by the time of the Second Reform Act, when the widening of the franchise more than doubled it, over 2,500 electors being registered for the 1868 general election which followed.But by the 1870s, electoral corruption had again become a problem in Boston.The result of the 1874 election was overturned for bribery, and a Royal Commission set up to investigate; when the next general election, in 1880, had to be declared void for the same reasons, Boston's representation was suspended for the remainder of the Parliament.
