There will be an estimated population influx of two million people to the capitol during the period of the games (27 June - 16 September).
Continuity Central warn that organisations should prepare themselves for disruptions due to the expected influx of journalists, athletes and tourists into the country.
It is estimated that there will be half a million extra public transport journeys in London a day. On top of this many major roads will be closed due to sporting activities and movements of people.
Paul Eskriett, Principal Security and Contingency Planning Advisor from The City of London Corporation, warned:
"It is essential that your organisation fully prepares for the event. There will be up to three hour delays on public transport, potential terrorist activity, criminal activity, public disorder and domestic extremism."
It seems that the best thing to do will be to leave town during the games.
