Properties owned by the Sharif family in London's upscale Park Lane neighbourhood were purchased in the 1990s and there has been no change of ownership since then, BBC Urdu reported on Friday.

According to official documents available with BBC Urdu, the four flats were purchased in the name of the Nielsen and Nescoll companies.

According to the documents, an official record of companies doing business in the United Kingdom reveals that when Hassan Nawaz established Flagship Investment Ltd in 2001, the address he provided at the time of registration of the company was that of his Park Lane apartment.

After the Panama Papers were published, Prime Minister Nawaz Sharif's son, Hussain Nawaz, had accepted the family's ownership of Nielsen and Nescoll. Hussain had said: "The Park Lane apartments in London are ours, two offshore companies, Nielsen and Nescoll, own these flats and I am the beneficial owner of these companies, working under a trust held by my sister Maryam Nawaz Sharif." -Business Recorder
