Labour's candidate for London mayor, Sadiq Khan, has said he would lead efforts to name a street after Holocaust hero Sir Nicholas Winton if elected to City Hall.
Mr Khan said that it was "right and fitting" that Sir Nicholas should be commemorated in the city where he was born.
He said: "Sir Nicholas Winton was a hero. He saved hundreds of Jewish and other children in the Czech Kindertransport, helping many of them to find homes and new lives in Britain.
"If elected mayor, I will lead efforts to find a suitable street or public space to name in his honour."
His pledge came in response to an American charity's suggestion for a memorial to Sir Nicholas, who died last year, aged 106.
Eduardo Eurnekian and Baruch Tenembaum, respectively president and founder of the International Raoul Wallenberg Foundation (IRWF), which promotes recognition of Holocaust rescuers, wrote to London mayor Boris Johnson .
They asked him "to consider the idea of naming a London street and/or public place" as part of their Houses of Life initiative, which is aimed at identifying and marking sites where victims of Nazism were given shelter
The IRWF also announced a plan to commission a bust of Sir Nicholas to be placed "in a symbolic venue", and asked the mayor to suggest a site.
Neither Mr Johnson or Conservative mayoral candidate Zac Goldsmith responded to the proposals.
Sir Nicholas, who was a stockbroker, rescued 669 children from Nazi-occupied Prague before the Second World War, arranging for trains to take them to London.
