Margot Robbie to heat up London for I, Tonya premiere

Oscar hopefuls Margot Robbie and Allison Janney will be sharpening their blades for the UK premiere of their new film I, Tonya.

The duo have both bagged Academy Awards nominations for their roles in the darkly comic biopic about disgraced figure skater Tonya Harding.

The first American woman to complete a triple axel in competition was ultimately banned from professional skating following the infamous attack on fellow Olympic competitor Nancy Kerrigan.

Robbie stars as Harding, and is nominated for best actress, while West Wing actress Janney, who plays her violent mother LaVona Golden, is nominated in the supporting actress category.

They will be joined at the premiere at the Washington Mayfair Hotel by director Craig Gillespie and writer Steven Rogers.

I, Tonya is released in UK cinemas on February 23.
