What needs to happen for the World Cup to be moved

The World Cup

Moving a World Cup is an incredibly difficult job but it has happened once before.

The future of the 2018 World Cup in Russia and the 2022 tournament in Qatar are in some doubt, as the Fifa corruption scandal goes on.

Swiss authorities are investigating the bidding process for each event.

Whoever replaces Fifa president Sepp Blatter will have to make a decision on whether to re-run the bidding process for both or one of the tournaments.

Russia losing the right to host the 2018 tournament would be a huge shock, and politically very dangerous. They have a decent footballing history too, which is more than can be said for Qatar. The decision to award that tiny gulf state the tournament has always seemed bizarre, and you could argue it started the process that led to Sepp Blatter's downfall. They have no footballing pedigree, scores of migrant workers have died in preparing the tournament venues and the difficulty in rearranging domestic leagues around the world to accommodate a first Winter World Cup means stripping Qatar of the right to host the 2022 tournament could be an easier decision for the next Fifa president, particularly as it would enable them to draw a line under Sepp Blatter's tainted reign.

FIFA

Why might the World Cup be moved?

The executive committee is the main decision-making body in Fifa which decides where the tournament goes.

It's made up of 24 people who get one vote each; a president, eight vice-presidents and 15 other members.

The members have been appointed by their own national federations.

At least five of the 14 people in Fifa arrested over corruption last week were on the executive committee at the time of the vote for the last World Cup.

This opens questions about the legitimacy of the vote and whether votes were bought for favours or cash.

Russia will host the World Cup

Will the 2018 World Cup be in Russia?

Most likely, yes. Stadiums have been built and the tournament is seen as too close to move.

The preliminary draw - to decide which teams will compete for the 31 available places - is also just a few weeks away.

Politically it would be a minefield, with tensions between the west and Russia rising over the conflict in Ukraine.

Russian President Vladimir Putin has called the events of the last week "odd" and aimed at taking the World Cup away from his country.

He said the arrests on behalf of the FBI were "another clear attempt by the US to spread its jurisdiction to other states."

Will the 2022 World Cup go to Qatar?

Much less certain. The tournament has had multiple problems preparing already.

Fifa have already expressed their disappointment that people have died while building the stadiums and many have criticised the wages and conditions migrants are given to work there.

Qatar beat Australia, Japan, the United States and South Korea to host the tournament in a decision that was greeted with shock.

The Football Federation Australia chairman Frank Lowy has said the race for the 2022 World Cup was "not clean".

In the last few days Qatari politicians have called the investigation into corruption in its World Cup bid "racist" and accused the West of being "anti-Arab".

Has it happened before?

Yes. The 1986 World Cup was scheduled to be held in Colombia.

Four years beforehand the South American country was hit by big economic problems and lost the backing to hold the tournament.

It was moved to Mexico a year later, giving them three years to prepare.

Maradona was the star, he also knocked England out, with one of the most controversial moments in World Cup history.
