The campaign to recruit volunteers for the 2018 World Cup and 2017 Confederations Cup was launched in June by Russian President Vladimir Putin and FIFA President Gianni Infantino.

"We are more than satisfied with the results of the [volunteer recruitment] programme," Sorokin told TASS following the passing of the deadline for submitting applications.

"We have received an overall of some 170,000 applications.

"This is the most impressive campaign by its scale in FIFA’s history."

In October of last year, the Russian Sports Ministry certified 15 higher education establishments in 11 cities across the country, officially authorising them to recruit and prepare volunteers for the Confederations Cup and the World Cup.

A total of 5,500 volunteers will be required for next year’s Confederations Cup, with applicants for the tournament required to be over the age of 18 by May 10.

The competition will take place from June 17 to July 2, with the quadrennial event acting as a key build-up event for the World Cup.

More than 15,000 volunteers will be required for Russia 2018.

Earlier this month, Infantino confirmed Russia will not be stripped of the hosting rights for the 2018 World Cup in the wake of the findings in the second part of the McLaren Report.

In an interview with German magazine Der Spiegel, Infantino stressed "boycotts and bans have never solved any problems".

The Swiss-Italian also said the worldwide governing body would assess the evidence presented in Canadian lawyer Richard McLaren's report, which found more than 1,000 Russian athletes had been implicated in a state-sponsored doping scheme spanning from 2011 to 2015.

Russia's staging of the 2018 World Cup - the bid process of which remains under criminal investigation - was also criticised during the UEFA European Championships in France this summer.

Calls had grown for FIFA to take the tournament away from the country as punishment for the violent behaviour of their supporters at the competition.

Russia’s Deputy Prime Minister Vitaly Mutko, a key figure in Russia securing the hosting rights to the 2018 World Cup, was accused of covering up a failed test from a top-flight player earlier this year.

The claims were made in a documentary from broadcasters ARD/WDR, entitled: "The Secret World of Doping: Showdown for Russia".

The fourth edition of the series produced by Hajo Seppelt, Florian Riese Wieck and Felix Becker, the first programme of which proved the catalyst in the doping scandal currently engulfing the nation, alleges former Sports Minister Mutko covered up a doping offence made by a footballer who plays for FC Krasnodar.

It is claimed the substance involved was Hexarelin, an anabolic steroid, and the failed test was recorded after Krasnodar beat FC Rostov 2-0 in 2014.

The case was not made public and the player involved was not banned, the documentary alleged, citing correspondences which appear to carry Mutko's signature.
