The Shepherd family bungalow in Corfu

Neil Shepherd, 38, was taken to the General Hospital in Corfu with his partner Ruth Beatson, 27, after they were overcome by gas at their hotel.

His daughter Christianne, seven, and son Robert, six, died on 26 October.

Greek police are considering whether a faulty boiler or air-conditioning system at the family's bungalow at the hotel could have been to blame.

A Foreign Office spokesman confirmed that Mr Shepherd had arrived in the UK on Thursday at about 9am, but it is not known whether Ms Beatson has also returned.

The hospital's manager had earlier said Mr Shepherd and Ms Beatson were on their way back to Britain.

The bodies of the two children arrived at Manchester Airport on Monday, accompanied by their mother.

Sharon Wood, 35, of Horbury, West Yorkshire, and her second husband Paul accompanied them on the journey after she had flown out to identify her children.

On Tuesday the permit of the Louis Corcyra Beach Hotel, where the family was staying, was suspended by the Greek authorities.

According to Tourism Minister Fanni Palli-Petralia, the hotel will permanently lose its permit if the ongoing police investigation finds that hotel officials were responsible for the deaths.
