Michael and Carole Middleton will be paying towards their daughter's wedding to Prince William next April.
The self-made millionaires have insisted on making a contribution to the royal event, and are said to want to pay for a specific aspect of the wedding, like the honeymoon, rather than make an overall contribution.
Experts are already making predictions about the cost of the big day, the majority of which will be paid by the Queen and Prince Charles.
Kate's dress is estimated to cost at least £40,000, while the cost of a cake - or cakes - to feed Westminster's 2,000 guests could cost anything between £10,000 and £50,000.
Flowers to fill the abbey and Buckingham Palace are expected to total between £200,000 and £500,000.
The cost of security and policing for the wedding, which could run into tens of millions of pounds, will be picked up by the tax payer.
