Poland's second city Krakow and Norwegian capital Oslo will both bid to host the 2022 Winter Olympics, officials behind the applications said Thursday.
Announced a week ahead of the closing date for submissions, the Polish bid would see Krakow in the south as the main host city but with events also held elsewhere in Poland and in neighbouring Slovakia.
"The rules allow two countries to team up in case the host country cannot accommodate certain sport disciplines," Slovak Olympic Committee chair Frantisek Chmelar told AFP.
Poland's Olympic Committee will submit the official letter on Thursday, its president Andrzej Krasnicki said.
The Oslo2022 committee for its part will "confirm our intention to be a candidate for hosting the games before the November 14 deadline," spokeswoman Ingunn Olsen told AFP.
The cities face tough competition from a long list of declared or expected candidates including Beijing, Munich in Germany, Almaty in Kazakhstan and Lviv in Ukraine.
The Polish bid would see Krakow host the opening and closing ceremonies and some ice skating events while the southern resort of Zakopane would be in line to host cross-country and snow-boarding competitions and Slovakia could host downhill skiing.
Poland and Slovakia have separately bid for past Winter Olympics to no avail, while Norway held the 1994 games in Lillehammer to great success.
The Oslo bid won the support of more than half of the city's population in a recent referendum, and according to local media has backing from Norway's culture minister.
The host town is expected to be announced on July 31, 2015.
The 2014 Winter Games take place in Sochi, Russia and the 2018 event in Pyeongchang, South Korea.
