Market Harborough, Northamptonshire which Nancy redecorated with help from Mrs Guy Bethell of Elden Ltd. In November 1933, Ronald was elected Member of Parliament (MP) for Harborough in Leicestershire. In the same year, the couple bought Ditchley House and Park near Charlbury, Oxfordshire as their home, and it was the decoration of this house which earned Nancy the reputation of having "the finest taste of almost anyone in the world."
