The Conservative manifesto disappeared from the party's website and was replaced with a "page not found" message before it later appeared.

Instead of the manifesto users were shown an Error 404 message, with the text: "Sorry. We couldn't find the page you were looking for."

Although a picture of the manifesto appeared on the website's homepage, the link was inactive.

The Queen's Speech - what is it?

It comes as thousands of protesters are expected to march on Downing Street in a "day of rage" to oppose Theresa May's government.

Ms May's party failed to secure a Parliamentary majority in the general election, forcing it to enter into talks with the Democratic Unionist Party to secure a "supply and confidence" deal.

However, Damian Green, the First Secretary of State, threw hopes of a deal into further doubt when he described it as merely a "possibility".
