Ian Pollitt, senior development surveyor at Peel who is charge of Liverpool Waters, said: “We have set up a steering group with the city council and Ian Wray to plan the visit.

“At the moment we have been told the 14 -16 of November, and we are currently waiting for confirmation of that.”

He said the Unesco inspectors were not just coming to see the site for the planned Liverpool Waters development, but the whole of the World Heritage site.

He added: “They are coming here to see that the council is capable of policing the World Heritage Site. Cllr Malcolm Kennedy, cabinet member for regeneration and the city’s appointed heritage champion, said he was proud of the way Liverpool is working to protect the WHS.

“I think what people have to do is come with an open mind, and examine what Liverpool is doing to enhance and protect the World Heritage Site.

“The World Heritage Site is not just about the Waterfront. It’s about William Brown Street, the Rope Walks and other areas.” He pointed to the recent reinstallation of the gates to the former Sailors’ Home, copies of other elements from it in a special garden in Liverpool One and the launch of a campaign in August to get companies to display WHS branding.

“It shows that we are doing something positive after years of relative inactivity.

“For me it is about the need to get the true picture across when they come.”
