Two senior figures at NFoPP are understood to have been put on gardening leave for three months.

They are believed to be Rob Clutton, the finance director, and Brian Schubert, the head of sales and marketing.

Schubert, who was formerly head of marketing at the RICS, has been with NFoPP for just over four years.

Clutton has been in his role for eight years.

Sources say they were escorted from NFoPP headquarters at Arbon House and that, pending investigations, they could return to their jobs.

When we tried to contact them at Arbon House, the telephone receptionist said that Clutton was not in the office and she did not know when he would be back.

Schubert was also said to be on holiday.

We have been unable to speak to either of them.

Yesterday, NAEA Propertymark chief executive Mark Hayward said he could not comment.

He told us: “We do not comment on internal staff matters.”
