Pictures show workmen installing anti-terror barriers and huge concrete blocks to protect the public around Wimbledon.

And armed cops have maintained a visible presence at the Henley Royal Regatta with security particularly tight today during the visit of PM Theresa May.

The beefing up of security comes after two terror attacks in London this year that saw a car and a van used to mow down innocent people.

Khalid Masood killed five people when he ploughed his vehicle into pedestrians on Westminster Bridge on March 22.

And a trio of Islamist fanatics massacred eight people using knives and a hired van in the London Bridge area on June 3.

The simple but deadly tactic is the latest favourite of brutal terror groups like ISIS, with several similar attacks across Europe over the last year.

And security chiefs in South West London look to be taking every possible step to prevent a repeat over the coming days and weeks.

Obstacles were installed around the car parks at Wimbledon, as well as the entrances and queuing areas, ahead of the start of the competition.

The queue at Wimbledon is one of the most famous parts of the prestigious tennis competition.

It sees people travel thousands of miles – often to camp overnight – to try and buy centre court tickets.

Last year it was said that a record-breaking number had lined up to get access to the event.

News of the security measures comes weeks after it was revealed Wimbledon may have been on the radar of the London Bridge terror ringleader Khuram Butt.

Wimbledon has also published security advice on its website, saying there will be a "proportional uplift in measures" at this year's Championships.

The "enhanced measures" include the use of sniffer dogs, CCTV, and thoroughly searching people, their bags and vehicles before entering the grounds.

As well as the usual knives and sharp objects, the tennis club has banned visitors from entering with selfie sticks, flasks, or any "objects or clothing bearing political statements".

Scotland Yard, which will be supporting Wimbledon staff with their security plans, also warned against touts who may be selling unauthorised tickets, and pickpockets who thrive in crowded areas.
