Police scour streets of Windsor in pre-royal wedding security operation

Police in Windsor have embarked on one of the most significant security operations in their history, as they scour the streets ahead of Prince Harry and Meghan Markle's wedding to keep more than 100,000 visitors safe.

Specialist explosive detection dogs from Thames Valley Police searched through the town examining letter boxes and phone booths for signs of potential devices.

With a month to go until the big day residents will notice more CCTV cameras, extra technology to recognise number plates and barriers to protect pedestrians from terror attack by cars or heavy duty vehicles.

In 27 degree heat on what has been the hottest day of the year so far Windsor town was heaving with locals and tourists coming to catch a glimpse of the Castle.
