One of the infrastructure fund managers behind London's super-sewer project has raised 66% more than its target - underlining investors' hunger for yield in a low-rates, post-Brexit world.

Listed infrastructure fund INPP said it had brought in £125 million in its latest capital raising, 66% more than the £75 million it had been targeting. Its announcement comes two days after US infrastructure fund manager Brookfield Asset Management said it had raised what it believes is the largest infrastructure fund ever - $14 billion - far in excess of its original $10 billion target.
