"Today I have written to Nicola Sturgeon".
Sturgeon's SNP may have secured 48 out of 59 Scottish seats in December's election, but the devolved Scottish Parliament in Edinburgh, where the party also dominates, requires permission - known as a Section 30 order - from Westminster in order to hold a second referendum on Scottish statehood.
He concluded: "It is time that we all worked to bring the whole of the United Kingdom together and unleash the potential of this great country".
"It is not politically sustainable for any Westminster government to stand in the way of the right of the people of Scotland to decide their own future and to seek to block the clear democratic mandate for an independence referendum".
"You and your predecessor made a personal promise that the 2014 Referendum was a "once in a generation" vote", he wrote to Sturgeon.
In a letter to Scotland's first minister, the PM said: "I can not agree to any request for a transfer of power that would lead to further independence referendums". They know that given the choice the overwhelming likelihood is the people will choose the positive option of independence.

The conclusion was that based on how the cosmic rays interacted with the grains, majority had to be about 4.9 billion years old. For Dr Heck, this latest research is one of the most exciting studies he's worked on, but he's sure it won't be the last.
Buoyed by his success in last month's UK-wide general election which saw him win a majority in Parliament, Conservative leader Johnson rebuffed Sturgeon's demands as he now looks ahead to Britain's withdrawal from the European Union - otherwise known as Brexit - on January 31.
Ms Sturgeon tweeted that the Tories - or Conservative party - were attempting to "deny democracy".
Boris Johnson's stalemate with SNP leader Nicola Sturgeon now threatens to damage his leadership, analysts say.
Sturgeon and her party have vowed to hold another vote on independence, a promise which was given greater urgency after Johnson's election victory signaled that the United Kingdom would follow through with Brexit.
Johnson says the 2014 vote settled the independence question and it would be divisive and bad for the economy to re-open the argument.
Ms Sturgeon immediately hit back at Mr Johnson, saying that the "Tories are terrified of Scotland's right to choose".
In an official statement issued later, Ms Sturgeon added "the Westminster union can not be sustained without consent" and that "democracy will prevail".
