By Tom Bergin and Mike Collett LONDON (Reuters) - It has never been done before and no defined procedure for doing it exists but, in theory, withdrawing the right to host a World Cup from a host nation should be an easy thing to do. Football has been in turmoil since a series of arrests last week of officials from the world governing body FIFA on U.S. Department of Justice allegations of bribery. Swiss prosecutors have also announced their own criminal investigation into the award of the 2018 World Cup to Russia and the 2022 tournament to Qatar. Source: Reuters
