Demonstrators gathered in London's Parliament Square Wednesday, protesting U.S. President Donald Trump's state visit to the U.K.

The protestors stood outside the Houses of Parliament with placards, flags and an inflatable Trump baby.

Speakers delivered addresses from a small stage.

They criticized the cost of the state visit, Trump's stance on Gaza and increased NATO defense spending.

The President and First Lady flew from London to Windsor, England earlier Wednesday, where they were welcomed by King Charles III and Queen Camilla.

In the grounds of Windsor Castle, Trump inspected the honor guards, toured the Royal Collection, visited the tomb of Queen Elizabeth II and exchanged gifts with the King.

He also watched a military parade which included a flyover from the Red Arrows.

Groups of protestors were also stationed in Windsor.

Later today, the Trump’s and members of the royal family will attend a state banquet.
