Police are beefing up security around Windsor Castle - the primary Royal residence - ahead of the Duke of Edinburgh's funeral.
Extra Armed officers will be on patrol and other security measures are in place to "help provide reassurance and keep local residents, businesses and visitors safe".
Thames Valley Police said it was carrying out “high visibility patrols” and the public would notice an “increased police presence, including armed officers, in Windsor during this national time of mourning”.
In a statement, the force said: “Windsor Castle is a primary Royal residency and we are expecting the town to be busier than normal, as people come to pay their respects.
“Additional officers will be patrolling the town centre along with the surrounding area to help provide reassurance and keep local residents, businesses and visitors safe at this sad time.”
Officers will be speaking to members of the public and are “on hand to answer questions”, it added.
Inspector Matt Lugg, who is co-ordinating the patrols, said they were part of measures to “ensure public health and safety” as officers expect an increase in the numbers of people in Windsor in the coming days, adding: “We would remind people to remain vigilant, and if they have any concerns or questions to approach us.”
Last week the force said it would deploy covert security tactics on Saturday when the duke is to be honoured with a ceremonial royal funeral at St George’s Chapel, in the grounds of Windsor Castle.
A statement said: “During this time of national mourning, there is an increased police presence and a broad range of security measures in place in and around Windsor.
“Some of these measures are visible, such as the extensive network of Automatic Number Plate Recognition (ANPR) technology, Close Circuit Television (CCTV) and Hostile Vehicle Mitigation (HVM) barriers, as well as our Mounted Section, whilst some measures are unseen.”
Police asked the public not to gather by Royal residences, avoid meeting in large groups, minimise travel and to make a donation to charity instead of laying floral tributes.
Reiterating the requests made by the Royal household and the Government, the force also pointed mourners towards an online book of condolence to pay their respects.
