Tyson Fury has been ordered to defend his WBC heavyweight title against Dillian Whyte.
Whyte has been named the "Gypsy King's" mandatory challenger by the sanctioning body and the two parties now have 30 days to agree a deal or purse bids will be called.
A war of words between the former sparring partners has been growing since Fury's knock-out defence of his title against Deontay Wilder in their trilogy fight in Las Vegas on 9 October.
Fury, who is represented by MTK - a sports management company linked to Daniel Kinahan - had a window of 30 days to set up a blockbuster undisputed clash with Oleksandr Usyk, who took the WBA, IBF, WBO and IBO titles from Anthony Joshua in September.
There had been talk of Joshua stepping aside to allow the two champions to meet in the ring, but Joshua triggered his contractual clause to force a rematch with the Ukrainian.
In the meantime, Whyte pulled out of an October bout with Otto Wallin. When Fury's 30-day deadline passed without an agreement to fight Usyk, the WBC did not immediately order the Whyte fight due to the challenger's ongoing arbitration dispute against them.
However, they have now done so and a all-British fight is likely to take place in February or March, with Cardiff and Manchester mooted as potential locations.
