Brits by the tens of thousands staged a massive protest against President Trump in London Friday, chanting, carrying venomous signs and flying an unflattering blimp depicting the commander-in-chief as an orange, diaper-clad baby.

“Dump Trump,” “Orange Lies” and “Trump Not Welcome” were among the printable slogans on the banners the protesters carried as they demonstrated against what they called the president’s bigotry, misogyny and anti-immigrant stance.

Another sign read “Trump wears poorly tailored suits,” while a man was selling rolls of “Trump toilet paper” emblazoned with a picture of the president.

Nicola Tanner, a 33-year-old public official from Bristol, took the day off from work to demonstrate.

Wearing a t-shirt with the word “RESIST” on it, she said it was great that the blimp had “touched a nerve” with Trump — and slammed her own government for rolling out the red carpet for the president, a frequent critic of the UK and its leaders.

“It’s embarrassing how much our government is falling over themselves to try to appease someone who has no interest in any sort of give-and-take in the UK-US relationship at all, and is so capricious he can change his mind between the end of one tweet and the start of the next one,” she told Reuters.

Miatta Marke, 43, came to the march with her daughter, 17-year-old Ambah.

“This is a reaction against the misogyny that’s evident in everything his administration does,” Miatta told NBC News.

“I thought it was important to bring my daughter today so we could be on the right side of history and not just screaming at the television.”

Trump, who arrived on Thursday, had said he would duck London as much as possible to avoid the protests, and groused about not feeling welcome.

“I guess when they put out blimps to make me feel unwelcome, no reason for me to go to London,” he told the Sun newspaper.

“I used to love London as a city. I haven’t been there in a long time. But when they make you feel unwelcome, why would I stay there?”

Trump blamed the protests on London Mayor Sadiq Khan, who gave protesters permission to fly the baby Trump balloon.

He also blamed recent terrorist attacks there on Khan, who is Muslim. The president claimed Europe is “losing its culture” because of immigration from the Middle East and Africa.

“Allowing the immigration to take place in Europe is a sham,” he said.

“I think it changed the fabric of Europe and, unless you act very quickly, it’s never going to be what it was and I don’t mean that in a positive way.”

Khan, whose grandparents hailed from Pakistan, responded by questioning why Trump repeatedly chose him to criticize.

“Paris, Nice, Brussels, Berlin. Cities in America all suffered terror attacks,” Khan told British broadcaster Sky News.

“And it’s for President Trump to explain why he singled me as the mayor of London out and not the mayors of other cities and leaders of other cities.”

About 1,000 people gathered to watch the blimp launch in Parliament Square, with organizers of the stunt wearing red suits and baseball caps emblazoned with “TRUMP BABYSITTER.”

After a countdown from 10, a cheer went up as the 20-foot high, helium-filled balloon — showing the president with a snarl on his face while clutching a cell phone — rose up.

It hovered about 30 feet off the ground, next to the Westminster parliament building and near the River Thames.

Organizer Daniel Jones, 26, a charity communications officer, said they were trying to make people laugh as well as making a serious point.

“It’s also about giving a boost to those in America resisting his policies,” he said.

Nearby, a man dressed as a gorilla and wearing a plastic Trump mask, stood inside a large metal cage.

Khan rejected suggestions this showed a lack of respect for the president.

“The idea that we restrict freedom of speech, the right to assemble, the right to protest because somebody might be offended is a slippery slope,” he told BBC radio.

“We have a rich history in this country of having a sense of humor as well.”

Many British politicians regard close ties with the States, which they call “the special relationship,” as a pillar of foreign policy and Prime Minister Theresa May had struck a conciliatory tone with Trump before the country’s departure from the EU.

But many Britons see Trump as crude, volatile and opposed to their values on a range of issues, from immigration to basic civility.

More than 64,000 people had signed up to demonstrate in London against the visit while other protests are expected around the country.

More protests are planned in Windsor, where Trump and first lady Melania Trump will meet the queen later, and in Scotland, where the president plans to spend the weekend at one of his golf courses.
