THERESA May was set to deliver a speech today on the binding nature of referendums that rewrote the history of the Conservative party and even her own voting record.

Speaking in Stoke-On-Trent, the Prime Minister claimed that the referendum on a Welsh Assembly was seen as binding despite narrow voting margins, drawing a clear parallel to the EU referendum.

The speech she delivered today, though, was different from the copy that was originally shared with the press.

May was due to state: "When the people of Wales voted by a margin of 0.3%, on a turnout of just over 50%, to endorse the creation of of the Welsh Assembly, that result was accepted by both sides and the popular legitimacy of that institution has never seriously been questioned."

However records show that the Conservative Party, and Theresa May herself, voted to scrap plans to create a Welsh Assembly following the referendum, by attempting to prevent a second reading of the Government of Wales Bill in December 1997.

In this instance the Prime Minister voted to amend the bill so as to prevent the formation of the Welsh Assembly and, failing that, voted a second time to prevent another reading of the bill.

May and the Conservatives failed in both instances to stop the bill moving on, and the Assembly was established the following year.

In 2005, the Conservative Party also promised in their election manifesto to hold a second referendum on the Welsh Assembly which would include the option to abolish it.

The altered speech instead changed the contentious line to "When the people of Wales voted by a margin of 0.3%, on a turnout of just over 50%, to endorse the creation of of the Welsh Assembly, that result was accepted by Parliament", erasing the Conservatives historical role in trying to prevent devolution.

In an attempt to stem growing support for a People's Vote, May went on to claim that we had never had a referendum in the UK that "we have not honored the result of".

This, too, is incorrect.

In 1979 a referendum was held on establishing a Scottish parliament which resulted in a majority backing devolution.

An amendment introduced by Labour MP George Cunningham ultimately scuppered the vote, after requiring that 40% of those registered to vote must have voted Yes for the referendum to be accepted.

Effectively, this resulted in any Scot who was registered to vote but didn't for whatever reason (eg if they were dead), being counted as a vote against.

Despite getting a majority, Westminster opted to ignore the result.

Following the second vote on devolution in 1999, which actually did result in the founding of Scottish Parliament, Theresa May also voted in favour of wrecking amendment to the Scotland Bill that would have prevented it.
