The seat had been held for the Liberal Party by members of the Wilson family since its creation in 1885, and the by-election was won by the Liberal candidate Guy Greville Wilson, who was the brother of the outgoing Member of Parliament (MP).
The seat had become vacant when the sitting MP Charles Wilson succeeded to his father's peerage as the 2nd Baron Nunburnholme. He had held the seat for less than two years, having been elected at the 1906 general election after the retirement from the Commons of his father Charles Henry Wilson, who had held the seat since 1885.
Three candidates contested the seat.
The Conservative Party candidate was Sir George Trout Bartley, a cockney who had been the founder of the National Penny bank and was MP for Islington North from 1885 until his defeat in 1906.
|Liberal||Guy Greville Wilson||5,623||36.2||−21.3|
|Conservative||George Trout Bartley||5,382||34.7||−7.8|
Bartley did not stand for Parliament again. Wilson held the seat (with much increased majorities) until the constituency was abolished in 1918. He then rejected the coalition coupon which he had been given, and was heavily defeated at the 1918 general election.
