The Liberal Democrats have doubled the size of their group on North Herts District Council, with Labour also making gains on a difficult election day for the controlling Conservatives.

District council chairman Alan Millard’s heavy defeat to Labour newcomer Mike Hughson in Hitchin Walsworth caused a major stir, with the authority’s unpopular £40 brown bin charge credited for swinging many votes away from the Tories.

In Letchworth South East, Labour won by just eight votes as former district council chairman John Booth lost to Kate Aspinwall.

But the big winners on the day were the Liberal Democrats, who went from three seats before the elections to six after – winning in Knebworth, Hitchin Highbury and Royston Heath wards.

The district council remains under Conservative control, albeit with a reduced majority. There are now 29 Tory councillors, 14 from Labour and six Lib Dems.

Sam S Collins, who won Hitchin Highbury decisively for the Lib Dems, told this paper: “With 47 per cent of the vote, I’m very aware that there’s more people who didn’t vote for me than people who did – and so I have to do a really good job. I’m here to work for everybody, not just the Lib Dem voters.

“Looking at the results across North Hertfordshire, it shows the people are thoroughly fed up with the Tories in North Herts. Three new Lib Dem councillors – we can make a big difference. We want to be the hardest-working councillors there are.”

Labour’s new group leader Martin Stears-Handscomb, who has replaced Frank Radcliffe, said the Conservatives largely had themselves to blame for the loss.

“The Tories locally got the double whammy of a government attacking local government and a fairly inept handling of one or two projects, including Hitchin Town Hall and the ongoing saga of Churchgate – which left them very vulnerable to local issues,” he said. “Like the ridiculous charge on the brown bins, which they didn’t need to introduce.”

Hitchin and Harpenden Conservative co-chairman David Leal-Bennett said North Herts Tories needed to “rethink how we interact with the voting public”.

“I think we have to listen to what the public have to say, and show them that actually we do listen – and we need to react to what their concerns are,” he said.

“When we have difficult decisions to make, I think we have to explain those decisions very clearly and very plainly. The fundamental thing is engagement with our electorate.”
