Malapportionment in the context of "Redistribution of Seats Act 1885"

The Redistribution of Seats Act 1885 (48 & 49 Vict. c. 23) was an act of the Parliament of the United Kingdom (sometimes called the "Reform Act of 1885"). It was a piece of electoral reform legislation that redistributed the seats in the House of Commons, introducing the concept of equally populated constituencies, a concept in the broader global context termed equal apportionment, in an attempt to equalise representation across the UK. It mandated the abolition of constituencies below a certain population threshold. It was associated with, but not part of, the Representation of the People Act 1884.
