Like the famous eroding coast of Holderness, Labour’s grip on political power is slowing crumbling.
Every 12 months or so, the Liberal Democrats take a bite-sized chunk out of the ruling group’s majority at the Guildhall. This week’s election was no different.
There was no Hartlepool-style cliff edge collapse for Labour. Indeed, the party even managed to secure an historic foothold in the traditionally blue heartland of Conservative Bricknell.
But the Lib Dems also managed to dislodge Labour heavyweights Peter Clark in North Carr and Dave Craker in Sutton.
They are now within touching distance of toppling Labour and, once again, can lay claim to winning the popular vote by securing more overall votes this week than Labour.
If anything, the election confirmed Hull as a two-party city when it comes to local politics.
However, a mini-surge in support for Conservatives also suggests that might not necessarily be the case in the future.
While Hull still awaits a Boris Johnson-inspired tsunami on its shores, the city’s political landscape underwent another polite tremor in this election.
Nothing earth-shattering but enough of a wobble to keep things interesting in the corridors of power in Alfred Gelder Street.
