However in the local elections of 1998 he lost by five votes, in a cliff-hanger election with three recounts. The result decided the overall control of the Council.^[4] He was encouraged to fight on by his friend Nicholas Bethell.^[13]

In 2002 he was elected as a London Borough Councillor for Harrow on the Hill,^[14] and at the same time the Conservatives narrowly gained control there.^[15] In nine years at Harrow he held roles in Performance and Finance, Education, and Children and Young People, and Chief Whip when there was a Tory majority of one.^[16] He served on the Deputy Lieutenants' Committee 2007-11,^[17] and due to his naval experience was the Council's representative on the Reserve Forces and Cadets Association.^[18] Outside council, Versallion was Chairman of Harrow Hill Trust Community Relations, a Director of Harrow Fields Gardens Estate Company, and a board member of the Harrow Heritage Trust.^[19]

In 2011, Versallion was elected to Central Bedfordshire Council for the ward of Heath and Reach.^[20] After his nomination as Bedfordshire's Portfolio Holder for Education in 2011, to avoid conflict of interest, Versallion himself ceded his place as a Councillor in London in order to avoid double responsibilities. He was appointed cabinet portfolio holder for Children's Services and Schools and resigned from Harrow Council.^[21][22]

In 2012-13 Versallion converted ten schools' age ranges, bringing to an end the decades-long arguments over the three tier education system in Bedfordshire. In 2014 he closed a further three schools.^[28] He was the subject of a government film on these changes.^[29] In 2015 national media reported that Versallion was planning to create a new grammar school in Bedfordshire.^[30][31]
