A dementia sufferer remarried his wife in a touching ceremony after proposing to her having forgotten they were already married.

Bill Duncan, 71, had been married to his wife Anne, 69 for 12 years - but suffered an onset of dementia that caused him to lose most of his memory and forget parts of their life together.

Convinced Anne was his new girlfriend, Bill proposed again last week.

Devoted Anne was sure he'd forget, but convinced she was his new girlfriend, smitten Bill persisted, and kept asking when they'd be walking down the aisle.

They tied the knot again in an emotional garden ceremony at their home in Aberdeen on Saturday, and Anne said they are as happy as ever.

"We'd been to a family member's wedding earlier in the month, and clearly it touched Bill as he turned to me not long after and said that he wanted to be with me forever," Anne said.

"He asked me when would we be walking up the aisle together, and I thought he would just forget he'd asked me that, but then the next day he said it again.

"I had some friends coming over on the weekend and thought that would be the perfect time to have our second wedding, if Bill still wanted to by then.

"Every day, he asked me about our wedding, and finally on August 17, I walked down the aisle with my wonderful husband, 12 years after our first wedding.

"Our friends pitched in to help with decorating the garden and providing a wedding cake, and my daughter Andrea convinced me to get a dress for the day too," she continued.

"We renewed our vows surrounded by a small group of our friends and family, and even added some bits in for Bill so it felt like he really was getting married.

"It was the most beautiful day, and being with our friends in the garden we share together made it all the more perfect."

The pair met in 2001 when Bill was working as an entertainer and magician in Aberdeen.

They married three years later, but Anne soon noticed Bill had started to forget things.

The pair visited the doctor and shortly after he was diagnosed with dementia.

His health began to slowly deteriorate and he started losing memory of precious moments, including their wedding day.

Anne became his full-time carer but Bill was convinced she was his girlfriend.

Anne added: "Bill has been so affectionate ever since I accepted his proposal, lavishing me in kisses and cuddles.

"Since his diagnosis, his displays of affection have become scarce, so to have all of this love radiating from him towards me has been truly wonderful.

"Our ceremony in the garden was very emotional, and I'm just so happy that he still loves me this much after all these years of battling dementia.

"Bill is a wonderful man and has always brought joy to other people's lives throughout his career as an entertainer, and he'll never stop bringing joy to mine."
