She entered the House of Lords, along with the diamond-studded imperial crown, which sat on its own velvet pillow.
Boris Johnson, who has yet to win a vote in the House of Commons as Prime Minister, has to get the support of nearly all the 28 Conservative MPs who voted against Theresa May's agreement if he manages to bring an agreement back from the European Union, together with support from the DUP.
Mr Johnson echoed the main points of the Queen's Speech in a written statement.
For the first time since becoming prime minister, he faces a choice that will see him embarrassed - or worse - whatever he does.
"There is still a lot of work to do", he said.
The discussions centered on future border arrangements between European Union member Ireland and Northern Ireland, which is part of the U.K. Johnson has put forward a complex proposal to eliminate the need for customs checks, but European Union officials say more work is needed.
Melanie Leech, chief executive of the British Property Federation, said the organisation welcomed the government's aspirations on the environment, infrastructure investment and greater regional devolution, but also highlighted how numerous bills are "predicated on Brexit and what form it takes".

At 11.30am, Ms Sarah Clarke, the Queen's representative to Parliament - generally known by her official title of Black Rod - marched to the House of Commons, the Lower, elected Chamber.
The Queen delivered her address in the presence of the Commons at the "House of Peers", outlining 26 new bills, most of which were anti-crime.
The so-called Queen's Speech is the highlight of a day of elaborate pageantry in Westminster and is used to detail all the bills the government wants to enact in the coming year. That would heap even more pressure on Johnson's embattled administration.
A spokesperson for the UK Prime Minister Boris Johnson said he would not resign even if parliament rejected his Queen's Speech.
Britain's Parliament is due to hold a Sunday sitting this week, for the first time since the Falklands War of 1982, to decide on the next steps after the summit.
If a Brexit deal is reached, it still needs to be approved by both the British and European parliaments.
The main sticking point remains the Irish border: how to prevent it becoming a backdoor into the European Union after Brexit without erecting controls that could undermine the 1998 peace agreement that largely ended three decades of sectarian violence.
"There has never been such a farce as a government with a majority of minus 45 and a 100 percent record of defeat in the Commons setting out a legislative agenda they know can not be delivered in this Parliament", said Jeremy Corbyn, leader of the opposition Labour Party, during a raucous debate later in the day.
