The US has been seen as the favourite to stage the competition, either as a standalone host or as part of a joint effort with their two neighbours. 

It now appears the latter option will be proposed, with the Confederation of North, Central American and Caribbean Association Football (CONCACAF) teasing that a "historic announcement" will be made tomorrow.

CONCACAF President Victor Montagliani, who also heads the Canadian Soccer Association, will be present at the press conference at the One World Trade Center.

United States Soccer Federation President Sunil Gulati and Mexican Football Federation President Decio de Maria will also take part.

The 2026 tournament will be the largest-ever edition of the World Cup after the FIFA Council agreed to expand the competition by 16 teams as part of plans spearheaded by FIFA President Gianni Infantino.

Forty-eight countries will be split into 16 groups of three, with the top two in each progressing to a 32-nation knock-out round.

Should the three nation bid be confirmed and earn hosting rights, a debate is likely on whether each should receive automatic qualification to the tournament.

CONCACAF will receive six berths under the new format, the same number as the South American Football Confederation.

There will be 16 European nations, one from Oceania, eight from Asia and nine from Africa, while a play-off tournament has been proposed to decide two remaining spots.

The likely joint bid comes at a time when US and Mexican relations are strained, after American President Donald Trump pledged to build a wall along the border in a bid to curb illegal immigration. 

Trump has also attempted to block travel to the US from a number of largely Islamic countries through executive orders.

Infantino has warned that nations considering bidding for the World Cup must allow any team who qualifies, and their supporters, access to the country.

The US hosted the World Cup for the only time in 1994, while Mexico staged the 1970 and 1986 tournaments, with the latter following Colombia's withdrawal.

Canada are yet to stage the competition and have only made one appearance to date, making a group exit after three straight defeats at Mexico 1986.

Confederation of African Football (CAF) President Ahmad Ahmad claimed last month that Morocco had the capability to host the 2026 tournament.

The African nation have unsuccessfully bid for the 1994, 1998, 2006 and 2010 World Cups.

A decision on the host of the 2026 World Cup is expected to be made in 2020.

Argentina and Uruguay have already expressed their interest in co-hosting the 2030 World Cup.
