Pippa Middleton will marry her fiance and hedge fund millionaire James Matthews tonight in what many have already dubbed the society wedding of the year.

Ms Middleton is due to walk down the aisle at approximately 10.30 tonight our time in a lavish ceremony in the British village of Englefield.

With a guest list of more than 300 people, the event will be one for the history books.

Mr Matthews, 41, proposed to Ms Middleton, 33, last July.

The couple have spared no expense on making sure guests will receive adequate protection and privacy.

The small English village is teeming with surveillance vans, security personnel and scores of police officers.

The security team have been hard at work setting up cameras around the entire venue, most of which have been hidden under camouflage material.

Four ex-special forces soldiers have been hired to run the entire 'operation'.

Men have also been spotted sweeping hedges with scanners looking for hidden cameras.

Spotlights have been placed around the huge glass wedding marquee, in an attempt to prevent paparazzi snapping shots successfully.

Local residents have also been given gold wristbands to identify them and have been told by security to put permits on their cars as well as carry ID.
