City centre roads will be shut for the groom to ride a ceremonial white mare.

He will be accompanied on the procession to City Hall on Saturday evening by tradiitional Indian dancers and an Indian brass band

It is hoped Ms Shetty will attend ahead of the midnight ceremony, conducted mainly in Sanskrit.

On Friday evening, Mr Aggarwal, 31, held a "night of song and dance" at his parents' home in Llandaff.

The internet entrepreneur said the three-day wedding programme, including 45 chefs who have been brought in from London to cater for an expected 1,000 guests over the three days, was organised in six weeks.

He said the couple had met "a few times over the years" as their parents were friends, and had begun courting four years ago.

"We used to play squash with each other. I used to gracefully lose," he said.

The wedding coincides with the celebrations for the Hindu holy festival of Diwali.
