He was elected as
Member of Parliament (MP) for
Halifax at the
1906 general election, and held the seat until the town's representation was reduced to one seat at the
1918 general election. He did not stand again in Halifax, but instead stood in the
Cannock division of Staffordshire, as a
Coalition Labour candidate (i.e. a holder of the
coalition coupon, supporting the
Lloyd George's coalition government). He won the seat, but lost it, standing as a
National Liberal at the
1922 general election. Parker was made a
Member of the Order of the Companions of Honour by King
George V in 1918. ==References==
