The battle for Britain's future played out Wednesday on London's River Thames.
The country's looming June 23 vote on whether to leave the European Union — dubbed a "Brexit" — has seen both sides of the debate ramp up their rhetoric and campaigning.
On Wednesday, both those backing a Brexit and those pushing for the status quo took to the famed Thames.
A flotilla of fishing boats backing a Brexit sailed under London's Tower Bridge. A counter-demonstration — with the help of singer and activist Bob Geldof — used dinghies and banners to spread the "In" message.
