Update: By all accounts, President Trump and Theresa May's final joint press conference was a success. Both sides discussed the nature of the 'special relationship between the US and the UK.

Trump reiterated that the US is committed to striking a "phenomenal" trade deal with the UK as it prepares to leave the EU, saying the deal has "tremendous potential" for the US and UK to improve trade by two to three times.

Of greater interest was the Q&A, where the British and American press corp were granted two questions each.

In his response to a question about his attacks on London Mayor Sadiq Khan, Trump described the protests in London as "very small" and "fake news", implying that those who had turned out were put there for political purposes. Asked whether she agreed with Trump about Khan being a "stone cold loser," May declined to answer.

Asked about a possible meeting with Labour leader Jeremy Corbyn, Trump said he decided not to meet with Corbyn, whom he described as a "negative force" in British politics. Afterward, Corbyn said he was "ready to engage" with Trump, a presumptuous statement that suggests Corbyn is already preparing to succeed the next Tory leader at No. 10.

Trump scoffed when asked about the possibility that Republicans might join with Democrats to block his tariffs on Mexican goods. The president cited his 90%+ popularity among Republicans, and said anybody who opposed his plan would be "mistaken" and "foolish."

It's "more likely" that tariffs will take effect next week

Brexit can and should happen, Trump said. Meanwhile, he added that the UK and US had reached a deal on Huawei that will allow them to work out their differences. A spokesman for May's office later said that the prime minister had told Trump that discussions within the British government were ongoing.

The two leaders will travel to France tomorrow to commemorate the 75 anniversary of D-Day.
