Thousands of protesters are expected in London today for May Day protests and demonstrations.
The Met police have already warned major businesses in the City of the potential for violent protests, and some businesses have taken precautions such as boarding up shop windows.
During May Day protests in 2000, a McDonalds restaurant was ransacked, along with several other businesses.
A website set up by May Day protesters has published a list of multinational businesses in central London, saying they are "sites for inspection."
Protesters are planning demonstrations outside Lockheed Martin and Shell oil this afternoon.
A march by the TUC will converge at Trafalgar Square.
The Met has deployed 4000 officers across the city, and set up a dedicated operations centre to control the policing effort, named Operation Benbow.
Nearly 100 people were arrested during May Day in 2001, with 54 arrested for various offences last year.
