Meghan Markle also said the income generated for the public purse ‘far outweighed’ the contribution of taxpayers’ money towards crowd security in May 2018.
The claim was made within the latest documents released as part of her High Court battle against The Mail On Sunday over an article which reproduced parts of a letter she had sent to her father Thomas Markle in August 2018.
UK taxpayers contributed to the estimated £32million cost of the wedding, although the church service, flowers and reception were paid for by the Royal Family.
The majority of the estimated figure – £30million – was funded by the taxpayer and mostly spent on security measures, including costs on protecting Windsor with a heavy police presence, crowd control and restrictions placed on businesses.

Meghan’s legal team said they had already confirmed that she had been ‘a working member of the Royal Family and to some (relatively nominal) extent publicly funded’.
Her lawyers also said the royal wedding was ‘not, in fact, publicly funded, but rather personally financed by HRH The Prince of Wales’ – Harry’s father Prince Charles.
The submission added: ‘Any public costs incurred for the wedding were solely for security and crowd control to protect members of the public, as deemed necessary by Thames Valley Police and the Metropolitan Police.’
However, consulting firm Brand Finance previously estimated that the royal wedding would provide a boost to UK tourism of only £300million.
The experts said at the time of the wedding that the £1billion figure would only be reached if other sectors of the economy such as retail and fashion were factored in.

It estimated an overall boost to the UK economy of £1.05billion, which also included £300million in public relations value, £250million for retail and restaurants, £150million for the fashion industry and £50million on merchandise.
Experts at Bridebook, who calculated the £32million wedding cost figure, also found that Meghan’s dress, the flowers, food and drinks came in at nearly £1million.
They said 20 silver-plated trumpets to announce the event would come in at £90,000 and the glass marquee for the evening reception would cost £300,000.
The lemon elderflower cake from Violet Bakery in East London was estimated at £50,000, while flowers at Windsor Castle cost about £110,000.

The Government also paid £1,084,512 to the local council for “stewarding, crowd control barriers, big screens, waste disposal, barriers and associated costs”.
Tourism authority VisitBritain also estimated that about 50,000 Americans were in the crowds lining the roads in Windsor and enjoying the atmosphere in London for the wedding.
