East Dorset in the
1910 general election. He lost by 426 votes to
Captain Guest but after a petition Guest was unseated. Nicholson stood again as a Conservative candidate in a
by-election against Guest's brother
Henry Guest but was defeated again by a small margin. In the
second general election of 1910 in December, he tried to get elected at
Stafford but was defeated by 755 votes. In 1921, he was elected the
Member of Parliament for the
Westminster Abbey constituency in a
by-election following the death of the incumbent MP
William Burdett-Coutts. He was re-elected in the following two general elections in
1922 and
