A group of London taxi drivers is planning to hold a series of demonstrations to voice their anger at being excluded from the Olympic Games Lanes.
The United Cabbies Group (UCG) says that the restrictions will prevent them from doing their jobs.
Nearly 90 percent of its members are in favour of taking action.
In comments posted on the UCG website, one member said that they would stage the "demo of all demos". Another said that they would "bring the place to a standstill".
