The 2018 speech is to be scrapped to give MPs time to deal with complex Brexit legislation, the government said.
But Mrs May was forced to postpone the official opening of parliament for two days - until 21 Wednesday - as she hammers out a formal deal with the DUP to prop up her minority government after falling nine seats short of the winning line in the 9 June snap election.
The change means the new Parliament won't break in the summer, giving significantly more time for committees to work, legislation to be scrutinised, and votes taken.
The move according to the leader of the House of Commons, Andrea Leadsom would help MPs as they scrutinise the "substantial amounts of legislation".
The leader of the Commons, Andrea Leadsom, said this would give MPs the maximum time possible to scrutinise legislation taking the United Kingdom out of the European Union, which means the government will not put forward a new legislative programme next year. This will double the length of the coming parliamentary session to two years.
Yesterday, the government announced parliament will sit for two years, instead of the usual one, as it prepares for Brexit. That decision, the first time it had been taken since 1949, was criticised at the time by Labour as an "abuse of power" aimed exclusively at easing the passage of controversial legislation.
"There's a lot of legislation to be gone through, we're leaving the European Union at the end of March 2019, so having a two-year period in which to bring together parliament and government, to really make progress on legislation that is essential to make a real success of Brexit".
The Queen's Speech was also dropped in 2011 under David Cameron's then-coalition government.
In the same statement, the government said it will aim to address the "deep-rooted inequalities in our society" following the deadly Grenfell Tower fire, which British police said on Saturday has likely claimed the lives at least 58 people.
Brexit negotiations start Monday, after British Prime Minister Theresa May lost her parliamentary majority in an election meant to strengthen her hand.
