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.
Having been on the police force for 27 years it's really something to be retiring from service on the weekend of the wedding. This is a large operation for any police force and one of the biggest I have worked on. We of course want it to all go smoothly and the focus be on the two people in love getting married.
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.
Hopefully everybody wants to just come together for the celebration and enjoy the wedding but seeing the police out like this is definitely reassuring.
