A London 2017 spokesperson told The Guardian organisers had offered to host the awarding of reallocated medals on August 11, but are waiting for final approval from the International Association of Athletics Federations (IAAF).

London 2012 Olympic champion Ennis-Hill is poised to receive a third global heptathlon crown having been upgraded from silver at the 2011 World Championships in South Korean city Daegu.

This followed Russia's Tatyana Chernova being stripped of her title following a Court of Arbitration for Sport (CAS) ruling in November.  

Chernova has appealed to CAS, but it is thought she has little chance of being successful.

Pavey, meanwhile, took possession last month of 10,000 metres bronze from the 2007 World Championships in Osaka after Turkey’s Elvan Abeylegesse, the silver medallist, was found to have failed a drugs test at the event in the Japanese city.

Final approval for the move to award medals retrospectively for the first time at the World Championships looks likely with IAAF President Sebastian Coe giving his backing.

"It should be done at a World Championships," he was reported as saying by The Guardian.

"These medals cannot just be sent recorded delivery.

"You might think I am joking but that is what has happened in the past.

"Athletes have had that moment ripped away, so the very least we can do is try to create the right platform to reverse that.

"We can't just say: 'Sorry about that, but here you go - you've got your medal now, take it down to your local pub'.

"They should be handed over in London."

Chernova was also stripped of the Olympic bronze medal she won at London 2012 as part of the same CAS ruling in November. 

The 29-year-old was also banned for three years and eight months following analysis of her athlete biological passport (ABP).

Chernova, also the Beijing 2008 Olympic bronze medallist, failed a test for anabolic steroid turinabol in January 2015.

This followed the retesting of a sample from the 2009 World Championships in Berlin in 2013.

She was given a two-year ban backdated from July 22, 2013 by the Russian Anti-Doping Agency (RUSADA), forfeiting all results recorded between August 15, 2009 and August 14, 2011.

This meant she lost a pentathlon bronze medal won at the 2010 World Indoor Championships in Doha, but she crucially hung onto her 2011 World Championship gold, won on August 30, 2011.

A second doping case was opened against Chernova in February 2016 with the IAAF referring the case to CAS to act as a first-instance decision-making authority.

This is due to the suspension of the All-Russia Athletics Federation due to the country's alleged state-sponsored doping scheme.

The CAS annulled all of Chernova's results between August 15, 2011 and July 22, 2013.

Her previous RUSADA-issued suspension was deducted from the ban handed out in November by CAS.

Abeylegesse is also set to be stripped of the two silver medals she claimed at the Beijing 2008 Olympics over 5,000m and 10,000m.

She was banned for two years in 2016 by the Turkish Athletics Federation after being revealed as one of 28 athletes for whom adverse findings were revealed by the IAAF.

This followed re-testing of samples from the 2005 and 2007 World Championships.

The IAAF confirmed the 34-year-old Ethiopian-born runner had failed a test during the latter, meaning her results from July 25, 2007 to July 25, 2009 were annulled.

Shalane Flanagan of the United States is set to be awarded Abeylegesse's Beijing 2008 5,000m silver, with Kenya's Linet Masai taking bronze.

Ethiopia's Meseret Defar is in line for 10,000m silver from the Games in the Chinese capital, while bronze will be claimed by Sylvia Kibet, also of Kenya.

Abeylegesse was second behind Tirunesh Dibaba of Ethiopia in the 10,000m at the 2007 World Championships.

London 2017 organisers have told The Guardian they are happy to find space in the timetable for all retrospective medallists from the retesting of samples at the 2005 and 2007 World Championships to be given special podium ceremonies.

This will depend, however, on whether the IAAF decides this will be required.
