Republican presidential candidate Mitt Romney is in Britain on the first leg of a week-long foreign tour that includes stops in Israel and Poland.
He is to meet political leaders and attend the opening ceremonies of the Olympic Games in the next three days.
The former governor of Massachusetts is not expected to make any policy announcements in London, but correspondents say the visit will give him the chance to show himself to the US electorate in the international arena.
…Critics have accused him of having a weak background in foreign policy, the same claim made about Mr Obama, who was a first-term senator during his 2008 White House campaign when he made a high-profile trip to the Middle East and Europe.
That tour culminated with a speech to hundreds of thousands of people outside the Victory Column in Berlin, Germany.
