(CNN) President Donald Trump has renewed his criticism of the new US embassy in London, ahead of a planned visit to the UK in July.

The billion-dollar embassy moved from its long-standing site in Grosvenor Square, central London, to its new home at Nine Elms, south of the city, in January.

But during a rally in Michigan on Saturday, Trump criticized the move. "We had the best site in all of London," he told supporters, before adding that now, "We have an embassy in a lousy location."

Trump told the rally that the previous site in Grosvenor Square was "sold for like 250 million" -- but that organizers "spent all of that money, plus a lot more, to build a new embassy in a lousy location."

The embassy's internal gardens are intended to represent the landscape of the Grand Canyon.

His comments come ahead of a planned visit to the UK on July 13, Trump's first trip to Britain since becoming President, the White House and Downing Street announced last week.
