Sir Elton John has failed to keep his promise to rebuild the life of a tragic Ukranian orphan, claims the boy's granny.

The singer and his partner David Furnish said their hearts were 'stolen' by 14-month-old Lev, when they met him in an orphanage in 2009.

After failing to adopt him, they publicly pledged to find him a home in his native country and send regular financial help.

Now the celebrities have welcomed their newborn surrogate son in the New Year in Los Angeles but Lev remained in the same orphanage in a bleak industrial town on the Russian border.

Accusing them of reneging on their promise, his grandmother, Yulia Ageyeva said she had heard nothing from Sir Elton in 15 months.

She said the singer had also promised to help Lev's four-year-old, HIV-positive brother, Artyom.

"I have not given up hope that Elton will fulfil his promise to help Lev and Artyom, but now he has his new American baby I doubt we will ever hear from him," the Daily Mail quoted Ageyeva as saying.

Last week Furnish said he and Sir Elton would continue with their attempts to find a Ukranian family for the brothers and had retained local lawyers to help them.

But it remains news to both Ageyeva and the orphanage.

"We know of no specific assistance," deputy director of the orphanage, Lyudmila Batikhina said.

"I don't know his reasons for forgetting. Maybe he made a big fuss over Lev for public relations, to show the world he was caring," Ageyeva added.

Sir Elton's rep declined to comment but said last night: "If you look through the cuttings you can see that Sir Elton has said he's financially supporting them". (ANI)
