Outsider Slovakia reached the Billie Jean King Cup final as doubles pairing Tereza Mihalikova and Viktoria Hruncakova completed a stunning comeback victory in Malaga, Spain, on Tuesday.

Emma Raducanu had given Britain the lead by beating Hruncakova in the opening singles but Rebecca Sramkova hit back for the Slovaks by upsetting Katie Boulter in three sets.

Mihalikova and Hruncakova then outclassed British pair Heather Watson and Olivia Nicholls 6-2 6-2 to send Slovakia into Wednesday's final against Italy.
