Who is the potential buyer of Fawley Court? The Marian Fathers have been coy about the deal. The estate agency cannot speak because it is client confidentiality. Even Fawley Court's neighbours have no idea.

We may have to wait until the end of the year when the UK Land Registry will have the details. The deal to buy the 50-acre site which is home to a prestigious estate, including a church and Polish community centre in Oxfordshire, is due for completion this month.

There have been rumours of a Persian heiress who "fell in love with the place".

On Radio ORLA's London Bridge show, Save Fawley Court campaigner Andrzej Zakrzewski pointed the finger on who is about to buy the Oxfordshire estate on Aida Hersham.

She has an address in Eaton Square in London, another in New York City, and is currently living in the tax haven of Isle of Man. Hersham, aged 45, has appeared in the New York Social Diary.

She has two children with her ex-husband Gary Hersham who for 20 years has run Beauchamp Estates one of the most exclusive Estate Agents in Curzon Street, London W1.

Aida Hersham although of the Jewish faith was on the board of the Catholic Hospital of St John & St Elizabeth until an abortion controversy led Cardinal Cormac Murphy O'Connor to remove people from the board.

Hersham's intentions for Fawley Court are unclear. Zakrzewski questioned whether it was suitable that Hersham buys Fawley Court.

And writing earlier this week, Save Fawley Court activist Bozena Karol asked: "Why was the Polish Catholic Mission's offer of £8 million not accepted when rumour has it that she (Hersham) has paid very much below the asking price of £22 million?"

But before the show went to air, Radio ORLA spoke with Jan Zyliński, who was one of the bidders trying to buy Fawley Court this year. He has been in real estate for many years and has a sizeable portfolio of properties already. He told London Bridge: "I have never heard of Hersham or her property interests. I am sure that if the sale happens, the new owners will register it in the name of an offshore company. There is no way to find out who is on the board. It is legal under international law, and that's how international capitalism works," he said.

Zakrzewski added: "I bow to Jan’s greater experience of these matters. And I have no doubt that the buyer will use the most tax-efficient means to buy."

If the buyer does not "pull out because of guilt, then there are two options open to us," Zakrzewski said. "We have already written to the Vatican asking it blocks the sale and we are ready to go to Rome to explain our under-represented position. And if that fails, we will seek to negotiate rights of way for the church in the Fawley Court grounds which is a protected building, a Listed, Grade II building."

Zakrzewski also said there were plans by the Marian Fathers to exhume the remains of Father Jozef Jarzembowski, the founder of Fawley Court’s Polish tradition in the 1950s.

He said it was an outrage, because Jarzembowski always said he wanted to be buried in the Fawley Court grounds.

Zyliński whose own father was the lawyer for Jarzembowski, said: "Father Jozef was a great man. And he will remain a great man wherever he is reburied. It is a decision which of itself is not material. Whether he will be in Fawley Court, in Ealing in London, or in Poland, he will still be a great man. The campaigners upset about Fawley Court are living in the past. They need to live in the future. We have lost Fawley Court, and as a patriot who loves Poland and the Poles, I am sorry if my remarks upset anyone."
