Two nurses who left a brain-injured man lying in urine soaked sheets and allegedly tried to "clean his feeding tube with a pen" have kept their jobs.

Grant Clarke was left paralysed down the left-hand side of his body after suffering a large brain haemorrhage in 2012. He was doubly incontinent and unable to swallow or communicate.

After visiting him at the west Kent Neuro Rehabilitation Unit in Sevenoaks in 2013, the 45-year-old's family became so concerned about his treatment they set up secret cameras.

Relatives noticed a significant change in the father-of-three's demeanour and he began to claim staff were mistreating him.

Mr Clarke's wife Binny, of Vernon Close, Sevenoaks, planted a covert camera in an iPod docking station which revealed the extent of the neglect.

Footage showed her husband being left to lie in his own urine for hours and staff pulling a help buzzer from his hands.

It also showed another nurse allegedly trying to clear his feeding tube with a ball-point pen.

Sections were aired on BBC Newsnight in 2013 and the footage appears to show nurses attempting to clean his feeding tube with a biro pen.

He is also given water five times over the space of two nights, despite being on a nil by mouth diet.

Family members also claimed staff spoke to Mr Clarke, who is the director of an IT company, very inappropriately and sternly.

As a result of the filming, three nurses from the unit were investigated by the Nurse and Midwifery Council through a tribunal.

They have now been found guilty of professional misconduct.

Two of the nurses, Marie Banwell and Sarah Corter, were given caution orders meaning they can still work with patients.

Miss Banwell admitted 13 charges but denied nine others, including attempting to clean Mr Clarke's feeding tube with a pen. This could not be proved by the panel.

She was given a caution order for 18 months.

Miss Coulter, a ward manager, also admitted 13 charges but denied four others including failing to understand the side effects of medication.

She was given a caution order for 12 months.

The third, Vanessa Kennard, faced ten counts including removing Mr Clarke's buzzer and telling his partner, Binny, he was too "buzzer happy".

She was suspended from practice for 12 months in her absence.

The unit where Mr Clarke is staying is part of Sevenoaks hospital.

Mr Clarke’s family lodged 26 complaints with the Kent and Medway NHS and Social Care Partnership Trust - 22 were upheld.

At the time issues were raised, a spokesman for the trust said it was "appalled" at the shocking footage and it apologised for its failings.

In a statement to Newsnight the trust added: "We subsequently created a robust action plan to address all concerns," and said that compulsory, specialist training for all staff had been introduced.
