Jasmine Paolini guided defending champions Italy to a third consecutive Billie Jean King Cup final by winning a gruelling three-set battle with Ukraine’s Elina Svitolina before sealing the tie in a decisive doubles encounter alongside partner Sara Errani.

Ukraine took the first point of the tie when Marta Kostyuk beat Elisabetta Cocciaretto 6-2 6-3 in the opening match.

However, Paolini fought back from a set down to beat Svitolina 3-6 6-4 6-4 before partnering Errani to a straight-set victory (6-2 6-3) over Kostyuk and Lyudmyla Kichenok.

Italy have won the BJK Cup on five occasions, with all of their triumphs coming since 2006, and reached a further two finals.

Sonay Kartal beat Ena Shibahara 6-3 7-6 (7-4) while Katie Boulter dropped just three games in her straight-sets victory over Moyuka Uchijima (6-2 6-1).

Speaking following her win, Boulter said: "The team deserves to be here and hopefully we can go to the final. Hopefully this is our time now."
