Who paid for Newhaven’s new welcome signs?

MAY I ask who paid for the new signs welcoming people to Newhaven and informing them we are now twinned with La Chapelle-Saint-Mesmin?

The previous signs were in good condition and were certainly not due for replacement.

I believe when twinning was first proposed it was stated this would be self-funding and would have no cost to council tax payers.
