George Michael's partner insists that police have not accused him of any wrongdoing in the star's death

For a man already suffering the raw pain of grief, Fadi Fawaz - the boyfriend of singer George Michael - has had a tumultuous week.

Fadi, who found the 53-year-old star dead in his bed at his Oxfordshire home on Christmas morning, is due to be questioned for the second time by police in a bid to piece together the events surrounding the last week of George Michael's life.

Detectives now suspect the singer died of a drugs overdose.

Fadi, 40, who had a five-year relationship with the star, has been angered by suggestions that he was a 'leech' on George, and also by claims that the couple had split up 18 months before the singer's death, the Daily Mail reports.

"We were very much in love, very much together," he told the Mail. "Why would I be there [in Goring-on-Thames] if we weren't together? I was there the last day of his life. I was there."

Fadi also insists that the police, who first questioned him over the death on Wednesday last week, have been "amazing" and "supportive". The former hairdresser, who has been trying to make a career as a photographer, told them he spent Christmas Eve with the singer but fell asleep in his car that night and only discovered that he was dead when he went to wake him the following morning.

When news of the death was announced on Christmas Day, George Michael - who had a history of drug abuse - was said by his manager to have died of "heart failure".

However, an initial post-mortem examination was inconclusive. Now toxicology tests will be done alongside a report for the coroner, aiming to discover what was behind his early death.

Fadi will be questioned again by police, who will be aiming to put together a full picture of the singer's movements and state of mind in the last week of his life, as questions continue to swirl around Fadi and why he slept in his car rather than in the singer's home on the night before George's death.
