The last remaining chunk of a toxic "monster" fatberg found in London's sewers has been unveiled at a museum.

Once weighing 130 tonnes and stretching more than 250m, the mass of congealed fat, wet wipes, nappies, oil and condoms has been conserved by the Museum of London and industry experts.

The display will run until 1 July.

Open to the public from Friday, the Fatberg! exhibition will tell the story of the nine-week battle to remove the massive blockage and its journey from the Victorian sewers in Whitechapel to the sealed display case it now rests in.

"It's important that we display things that reflect the highs and lows of living in the city," curator Vyki Sparkes said.

"Fatbergs are disgusting, fascinating things which mark a particular moment in London's history, created by people and businesses who discard rubbish and fat which London's Victorian sewer system was never designed to cope with."

Thames Water's Becky Trotman added: "This display is a vivid reminder to us all that out of sight is not gone forever, so please help keep London and all the sewers flowing - don't feed the fatberg."
