We expect to find out who will be the first West Midlands mayor between 14:00 and 18:00 today.
Things will depend on whether there is a clear winner after the first preference votes are tallied or whether the electorate needs to wait to see what the second preference votes turn up.
Whoever is elected, they're going to head a West Midlands Combined Authority made up of seven constituent member councils - Birmingham, Coventry, Solihull and all four Black Country boroughs of Dudley, Sandwell, Walsall and Wolverhampton.
They will have powers over economic development, education and skills, housing and transport - including compulsory purchase powers.
The mayor will control a £1.1bn investment fund over 30 years, or £36m a year. The costs of the mayor's office itself will be covered by this fund until April 2018.
That money is handed down from government.
