The Kevin Johnson World Tour is stopping in London this week.
The mayor is attending the World Tourism Market, one of the largest tourism trade shows in the world. He is part of a team of California tourism officials and celebrities marketing the state to tour operators from around the world.
Local tourism officials and the mayor's office are touting Johnson's appearance as a marketing gold mine for the city. But it also means Johnson will likely miss his 10th City Council meeting of the year.
Johnson was originally scheduled to arrive back home on Wednesday. He may cut the London trip short to get back in time for Tuesday night's council meeting.
The mayor arrived in London over the weekend. Part of the event was the premier of a documentary about California at the Royal Opera House, a film that features Johnson and 11 other Californians.
Stephen Hammond, president of the Sacramento Convention and Visitors Bureau, said "there is no better ambassador for the city of Sacramento than Mayor Johnson."
"In addition to being the mayor, he is a celebrity because of his NBA all-star status and basketball is huge in Europe," Hammond said.
Beyond the conference, Johnson toured the O2 arena in London. That facility was built by ICON Venue Group, which is helping to lead Sacramento's arena plan.
The mayor's trip is being paid for by the tourism industry, not city money, his office said.
