The Lib Dems deputy leader Simon Hughes has called on the water regulator Ofwat to reject a request from Thames Water to raise their prices to pay for the Thames Tideway Tunnel.
Thames Water customers should not be expected to pay a huge amount towards the tunnel, given that in the years immediately before making this request, it had assets of billions of pounds which they have paid in dividends to their shareholders.
A spokesperson for the Liberal Democrats confirmed that the party would present an alternative method of paying for the Thames Tideway Tunnel later this month.
Britain's biggest water company appeals to the water regulator to be allowed to charge its customers an extra £29 on top of their bills.
Thames Water made profits of £150m last year, and gave shareholders £92m - so why is it wanting to charge customers an extra £30?
