Nigel Farage has blasted Downing Street for being negative over Brexit, as he insisted he could be Britain's go-between for Donald Trump's government.
The interim Ukip leader wrote the "joyous" EU referendum result was "the first brick knocked out of the establishment wall", but the Government had not changed accordingly.
He said: "The political revolution of 2016 now sees a new order in charge of Washington.
"In the United Kingdom the people have spoken but the players at the top have, I am afraid, stayed the same.
"Those who supported Remain now hold senior positions. Worst still, those who were openly abusive about Trump now pretend to be his friend.
"It is career politics at its worst and it is now getting in the way of the national interest."
Mr Trump came out in support of the interim Ukip leader his week, tweeting that he would do a "great job" as Britain's ambassador in Washington.
Suggestions have been repeatedly dismissed by the Government.
But Mr Farage argued that giving him a role would be in the national interest.
He wrote: "I would do anything to help our national interest and to help cement ties with the incoming Anglophile administration.
"At every stage I am greeted by negative comments coming out of Downing Street.
"The dislike of me, UKIP, and the referendum result is more important to them than what could be good for our country.
"I have known several of the Trump team for years and I am in a good position with the President-elect’s support to help.
"The world has changed and its time that Downing Street did too."
