Hudson returned to Italy when appointed by the 1852–55 UK
coalition government to the British Legation at
Piedmont, specifically to promote
representative democracy. He developed a close relationship with
Camillo Cavour, Prime Minister of
Piedmont-Sardinia, later the first Prime Minister of a united Italy, and other leading Italian liberals, Giuseppe Massari,
Marco Minghetti,
Bettino Ricasoli,
Giovanni Morelli and
Verdi, which caused
Lord Malmesbury, Foreign Minister of the 1858–59
Tory administration, to describe Hudson as "more Italian than the Italians themselves", and Victoria to express her displeasure at his closeness to the Italian liberal cause. Hudson's intimate association with Italian patriots was seen as too partisan for a man in his position, however, Malmesbury understood Hudson's reluctance to act in a way that could prevent a war (between
France and Austria) that could lead to unification The same year, a description of the Legation was given by the wife of the secretary to the
Prussian Minister at Turin who had heard of the richness of Hudson's home; she compared it favourably to other Turin legations, mentioning "beautiful things" and Hudson's devotion to paintings. At the end of his tenure Hudson sold the Legation artworks, but gave a
Titian copy, ascribed to
Poussin, to Verdi and a
Jacopo de' Barbari to Layard. ==Later life==
