Most Fifa members around the world, with the exception of Russia and the Asian members, are to find out today what teams they will face for the 2018 World Cup qualification.
Gibraltar, a member of Uefa (which is why it's taking part in the Euro 2016 qualifying), is not a member of FIFA so will not be taking part. Russia, as the host nation, qualifies for the tournament automatically so will also not be taking part in the qualifying.
208 Fifa members are to take part in qualifying for the 21st FIFA World Cup including, for the first time, Bhutan and South Sudan. 141 nations are to take part in today's draw.
Four of the FIFA members who are to find out today what teams they will face including, of course, the UK's four sides: England, Scotland, Wales and Northern Ireland.
England and Wales - ranked 9th and 10th in the world respectively - are two of the top seeds in the European (Uefa) section of the qualifying, but that means that, whilst they cannot be drawn in the same group as each other, each could end up being drawn in the same group as either France (ranked 22nd in the world) or Italy (ranked 17th in the world), each of whom are second seeds. One side from each seed goes into each group.
Despite the fact that the main qualification draw takes place today, qualifying matches have already taken place in the Asian section (AFC) of the qualifiers (which also includes Australia), so those teams involved in that will also not be part of this draw. The first goal of the 2018 World Cup qualifiers was scored by Chiquito do Carmo for Timor-Leste on 12th March in their 5-1 aggregate win over Mongolia.

2018 World Cup draw
Venue: Konstantinovsky Palace, St Petersburg Date: 25 July from 16:00 BST
Coverage: Live on BBC Red Button and online; Live text commentary on BBC Sport website and app
The Home Nations will find out who they will face when the qualifying draw for the 2018 World Cup takes place on Saturday in St Petersburg, Russia.
England, Wales, Scotland and Northern Ireland are among 141 nations who will be in the draw.
European sides will be placed into nine groups - seven with six teams and two of five sides - with Roy Hodgson's side knowing they will be in a pool of six.
The draw, at 16:00 BST, is live on the BBC Sport website and Red Button.
Konstantinovsky Palace, St Petersburg
How does the European draw work?
Russia have already qualified as hosts, and the other 52 member nations have been split into six pots based on Fifa's July rankings.
Gibraltar are not involved as they are not a member of Fifa, despite being a Uefa member.
The nine top seeds in Europe - including Wales and England - will first be drawn into a group. For TV rights purposes, England, Germany, Spain and the Netherlands will be drawn into groups of six teams, as will Italy and France from pot two.
A team from each of the other four or five pots will then be drawn into each group to make up the nine groups. Games will be played from September 2016 to October 2017.
The nine group winners will progress to the finals, while the eight best runners-up will take part in play-offs in November 2017.
The Fifa confederations of Africa, Oceania, South America and Concacaf (North, Central America and the Caribbean) will also be involved.
Germany are the holders of the World Cup after a 1-0 extra-time victory over Argentina in Brazil in 2014.
Fifa has announced that former Chelsea midfielder and Russia captain Alexey Smertin will replace Brazilian striker Hulk as a draw assistant "due to the Brazilian's club commitments" with Zenit St Petersburg.
Earlier this week Hulk said racism happens at "almost every game" in the Russian league.
The first game of the 2018 World Cup qualifiers was between Timor-Leste and Mongolia on 12th March, with Chiquito do Carmo scoring the first goal in a 4-1 victory for Timor-Leste over Mongolia. Timor-Leste went on to win the two-legged tie 5-1 on aggregate.

What are the best - and worst - scenarios for the Home Nations?
As top seeds, England (currently ranked 9th in the world) and Wales (10th) have guaranteed avoiding the other top sides in Europe. Theoretically.
However, from pot two they could still face Italy (17th) or France (22nd), while trips to the likes of Sweden (33rd), Poland (30th) or Ukraine (27th) could prove tricky.
Wales, Northern Ireland (37th) and Scotland (29th) could be drawn into a group of five teams instead of six - which may help their chances.
