Some tiny treasures from the Thames last week. The oldest is a clay tobacco pipe bowl, stem is missing, but dating from 1640-1680. Partial Georgian-era buckle, made from pewter, possibly from a shoe. Eurocoin token for a slot machine and a brass/paste brooch, shaped like a bow, could be 1950s.

It was fantastic to invite Sir Geoffrey Clifton-Brown, chair of the Public Affairs Committee and MP for North Cotswolds, to see our water quality testing in action at Wealdstone Brook in North London.🧵⬇️

These latest findings from the Environment Agency are deeply concerning. For over a decade, we’ve seen warnings about declining water quality and ecosystem health — and yesterday’s results show that the situation is worsening, not improving. 🧵⬇️
