In February 2007, Ken Livingstone signed a deal with Venezuela to provide cheaper oil for London buses. In return, the Greater London Authority advises Venezuela on recycling, waste management, traffic and reducing carbon emissions. This deal came under criticism from the London Assembly Conservatives including Richard Barnes, who stated that the "money would be better directed at the poor of Venezuela," and journalist Martin Bright, who said that the deal "effectively takes from the poor of Latin America to give to one of the richest cities in the world." Prices have been slashed by 20%; following this, half-price bus travel became available to Londoners on income support. Livingstone stated the plan "rises on the suggestion of President Hugo Chávez and builds on the work his government is doing around the world in tackling the problems of poverty," and also said, "This will make it cheaper and easier for people to go about their lives and get the most out of London. The agreement... will also benefit the people of Venezuela, by providing expertise in areas of city management in which London is a world leader."
