A batch of listings has been investigated by Zoopla. The portal said the listings had been uploaded for the first time on Tuesday.

EYE had sent Zoopla a number of what looked like suspicious listings.

The portal named no names, but last night Zoopla told EYE: “These listings were uploaded to our website yesterday for the first time and as soon as we became aware of them we contacted the relevant agent member for verification.

“We take these matters very seriously and have a dedicated compliance team whose sole job is to protect the integrity of our listings and will ensure that the appropriate action is taken asap.”

Separately, Rightmove has announced an inquiry into so-called portal juggling.
