The snakes, which are frequently seen by Regent’s Canal, can grow up to 2m long and have been spotted feasting on rats and birds.

They are thought to have escaped from London Zoo in the 1990s.

Speaking to the Camden New Journal, London Invasive Species Initiative (LISI) manager, Karen Harper, said there was a strong case for the snakes to be culled.

“At present there is limited information on what effects the species may have on our local ecosystems,” he said.

However, wildlife supporters and ecologists have urged LISI to let the snakes be, as they are ‘almost certainly non-problematic’.
