Anni-Frid Reuss, a former member of legendary Swedish pop group Abba, has demanded the repayment of a multi-million euro (dollar) loan she made to a Qigong centre, her lawyer said Wednesday.

The former pop star has asked for the 46 million kronor (4.9 million euros, 6.9 million dollars) she had lent the Yantorp Qigong resort in southern Sweden be returned, Carl-Gustaf Söder told AFP.

Reuss, known as Frida to Abba fans, has also said the company should be liquidated to allow her to recuperate her money, he added.

The Yantorp Qigong resort, which comprises a hotel and a temple and offers traditonal Chinese medicine and meditation, meanwhile insists the money was a donation from Reuss.

"Its a shock. We are all very sad," temple leader Marcus Bongart told the Expressen daily."

He said the money "was anything but a loan."

"Frida wanted to support us here in our project and the valuable ideas that exist here. She has been a friend for 20 years," Bongart said, adding, "we have been conned."

Soeder meanwhile described Bongart's reference to a donation as nonsense, saying he planned to take the case to court in the southern city of Malmö.
