PRINCESS Eugenie’s big fat Royal wedding to long-term boyfriend Jack Brooksbank will allegedly leave the taxpayer with a massive clean-up bill.

It has been claimed that the cost of cleaning up Windsor following the nuptials will be in excess of £250,000.

According to the Mirror, this additional expense is set to be met by the British taxpayer, and will cover the cost of mobile toilets, stewards and barriers along the open-top carriage ride route as well as the post-wedding clear-up operation.

The additional expenses will be added onto an already extortionately expensive wedding for the ninth in line to the throne.

The 28-year-old daughter of the Duke of York and Sarah Ferguson is due to marry her long-term beau, tequila brand ambassador Jack Brooksbank, on October 12 at St George’s Chapel.

It is the same location where Prince Harry married Meghan Markle in May.

Princess Eugenie’s wedding was initially costing around £750,000 and was set to be paid for by the couple’s parents.

However, amid increased fears of a terror attack in the UK, this has now more than doubled to almost £2million – with the extra funding coming from the taxpayers.

That’s because the princess will require extra firearms officers in attendance on the day to provide tighter security.

The extra money will draft in officers on overtime rates, with some cancelling their holidays to be on guard.

Dozens of officers will also be required to search the open-top carriage procession route in advance and there will be a blanket ban on drones flying over the event too.

The Mirror also claims that Windsor and Maidenhead council will be contributing to the bill, in the hope of later being reimbursed by central government.

While royal fans are excited to catch a glimpse of Eugenie and Jack, more than 35,000 citizens have signed a petition demanding demanding that no public funds should be spent on the nuptials.

Anti-monarchy group Republic launched the petition online, arguing that "this royal wedding is a private, personal event" which is being "dressed up as a national occasion."

As Eugenie "carries out no royal duties", the organisers of the petition claim "there is little public interest in another royal wedding".

They're calling upon the government to "publish a report of all costs to taxpayers".

The petition has received more than 37,700 signatures as of October 9 but requires 100,000 before it will be brought to parliament for debate.
