Maryland Gov. Martin O’Malley is headed across the pond for a pair of talks about politics and government.

O’Malley (D) departed for London on Tuesday, aides said, with plans to give a talk at a think tank Wednesday on the future of progressive politics in the United States. On Thursday, he is booked to talk at another think tank about his pioneering use of CitiStat, a statistics-driven governing tool, while mayor of Baltimore.

The trip, which aides said is not being paid for with taxpayer dollars, comes as O’Malley weighs a 2016 White House bid.

He is expected to be back in the country in time for planned appearances Saturday in South Carolina, where he is scheduled to campaign alongside Vincent Sheheen, that state’s Democratic gubernatorial nominee this year.

The Policy Network, which is hosting the first event, notes in a promotional blurb that Maryland has “made notable progress in a number of defining public policy areas.”

O’Malley’s billing for the second event, hosted by the Centre for Cities, says he will “discuss his experiences of using data to support economic growth during his time as Mayor of Baltimore.” O’Malley served as mayor from 1999 until becoming governor in 2007.
