 Boston had its right to vote restored for the 1885 election, but the boundary changes which came into effect at the same time slightly reduced the size of the borough and allowed it only one MP.The constituency at this period was mainly middle-class but non-conformists had a strong presence, enabling the Liberals to be competitive where they might otherwise have struggled.The deciding factor which may have tilted the constituency towards the Conservatives in its final years may have been the benefit that the local fisherman saw in Tariff Reform.
