A property developer has claimed he has spent more than £1million tackling Japanese Knotweed.

Dorian Payne, a developer in Wales, claimed he encounters the destructive weed, which can grow to heights of more than 10feet and sprouts through tiny cracks, at almost every property he takes on.

Japanese Knotweed can tear through brickwork and concrete if left to spread at will and, over time, can take over gardens and cause long–term damage.

Across the UK, there are now over 100,000 infestations recorded annually with this summer seeing a huge spike in cases.

Mr Payne, 30, spoke to the Daily Mail during a break from fighting the Knotweed on his current job in Newport and revealed it's the number one issue he faces when starting a new project.
