The pair, who triumphed in Beijing in 2014, sealed top spot in the five-team round-robin group with a 2-0 victory over Great Britain’s Sue Gilroy and Megan Shackleton at the Slovnaft Arena. 

They made the perfect start by winning the doubles 12-10, 11-5, 11-3, before Peric-Rankovic overcame Shackleton 11-5, 11-2, 11-6 to bring matters to a conclusion and ensure an unbeaten record.

Peric-Rankovic, the individual class four Paralympic champion, and Matic were part of the squad which won the team silver medal at Rio 2016.

They were joined by Kristina Arancic for the competition this week at the Slovnaft Arena. 

"We are very happy that we were able to defend our title from three years ago,” Peric-Rankovic said.

"For us, the aim has always been to stay at the highest level and maintain if for a long time.

"It always feels nice to be crowned world champion."

Defeat for Gilroy and Shackleton saw them finish in third place behind Germany’s Sandra Mikolaschek and Lisa Hentig, who beat them 2-0 earlier in the day.  

Mikolaschek and Hentig rounded out their campaign with a 2-0 win over home favourites Alena Kanova and Katarina Dobrovodska, meaning their only defeat was the 2-1 reverse against Peric-Rankovic and Matic yesterday.

Elena Prokofeva and Maria Galkina clinched the women’s class 11 title for Russia with a 2-0 win over Hong Kong’s Ng Mui Wui and Wong Pui Kei.

The doubles was secured with an 11-2, 11-7, 11-7 success, before Prokofeva beat Wong 2-11, 11-4, 11-4, 11-5 to seal the title.

Hong Kong, who were also represented by Ka Man Wong, finished in second place by virtue of a superior match ratio between the three teams who finished level on one win from three outings. 

Their ratio of 3-2 was better than that of France's Magali Rousset and Lea Ferney, 3-3, and Japan's Yumi Ono, Harumi Kimura and Kanami Furukawa, 2-3.

In the men’s class 11 event, France ensured top spot after maintaining their unbeaten record with a hard-fought 2-1 victory over Australia.

Rory Carroll and Samuel Von Einem gave Australia the advantage by beating Lucas Creange and Antoine Zhao 14-12, 11-6, 8-11, 7-11, 11-9.

France recovered though with Creange defeating Von Einem 11-7, 11-4, 13-11 and Zhao overcoming Carroll 11-7, 13-15, 11-8, 11-8 to conclude the contest. 

Hong Kong, who selected from Wan Wai Lok, Leung Chung Yan and Tsoi Ming Fai, came second and were followed in the standings by the Australians.
