Former Fifa president Sepp Blatter says the decision to award the 2022 World Cup to Qatar was a "mistake".

Blatter, 86, was president of world football's governing body when Qatar was awarded the tournament in 2010.

The Gulf state has been criticised for its stance on same-sex relationships, human rights record and treatment of migrant workers.

"It is too small of a country. Football and the World Cup are too big for it," he told Swiss newspaper Tages Anzeiger.

The Qatar World Cup, the first to be hosted in the Middle East in the tournament's 92-year-history and the first during the Northern Hemisphere winter, takes place from 20 November to 18 December.

Fifa's executive committee voted 14-8 for Qatar to host the tournament ahead of the United States 12 years ago, at the same time Russia was awarded the 2018 event.

Blatter says he voted for the United States and blames then-Uefa president Michel Platini for swinging the vote in Qatar's favour.

"It was a bad choice and I was responsible for that as president at the time," he said.

"Thanks to the four votes of Platini and his [Uefa] team, the World Cup went to Qatar rather than the United States. It's the truth."

Blatter also said Fifa had adjusted the criteria used to select host countries in 2012 after concerns were raised about the treatment of migrant workers building World Cup stadiums in Qatar.

"Since then, social considerations and human rights are taken into account," he added.

Blatter spent 17 years as Fifa president but was forced to step down in 2015 over allegations he unlawfully arranged a transfer of two million Swiss francs ($2.19m; £1.6m) to Platini, who was also forced to resign from his position at Fifa.

He was originally banned from football by Fifa for eight years, later reduced to six, over the Platini payment. In March 2021 he then received an additional ban until 2028 for "various violations" of Fifa's code of ethics.

Blatter and Platini were charged with fraud last November but were found not guilty at a trial in Switzerland in July.

The decision to award the 2018 and 2022 World Cups to Russia and Qatar respectively has been dogged by accusations of widespread corruption, with two investigations launched by Swiss prosecutors and the US Department of Justice in 2015.

Qatar and Russia have always denied any wrongdoing, and both were effectively cleared by Fifa's own investigation in 2017.

Fifa recently wrote to competing nations asking them to "now focus on the football" instead of the competition's controversial build-up.

The Fifa letter was criticised by Human Rights Watch, Amnesty International and LGBTQ+ campaigners in England and Wales, while 10 European football associations - including those of England and Wales - said "human rights are universal and apply everywhere".

There is concern about how LGBTQ+ people are treated in Qatar, where same-sex relationships and the promotion of same-sex relationships are criminalised, with punishments ranging from fines to the death sentence.

Amnesty International says that since 2010, hundreds of thousands of migrant workers have faced human rights abuses while employed to build wider infrastructure necessary to host the tournament.

Peaceful protests have been planned by some players, while England's Harry Kane and nine other captains of European teams will be wearing 'One Love' armbands. to promote diversity and inclusion.

Denmark will wear "toned-down" shirts to protest against Qatar, with kit provider Hummel saying it "does not wish to be visible" in a tournament it claims "has cost thousands of lives", while Australia's squad have released a video urging Qatar to abolish its laws on same-sex
