UKIP leader Nigel Farage was escorted from an Edinburgh pub in a police riot van after being mobbed by rowdy protesters.
Nigel Farage said the focus on immigration and aspiration in the Queen's Speech showed that UKIP is "changing the UK national debate."
There is no question that the day belongs to UKIP and Nigel Farage. The party has gained over 100 seats and won about a quarter of the vote.
UK Independence Party leader Nigel Farage has moved to exploit unrest within the Conservative Party with a rallying call for disaffected Tory voters to join his ranks.
Mr Farage has taken out a full-page advert in The Daily Telegraph urging those unsettled by David Cameron's policies or insulted by a senior Tory figure's alleged description of activists as "mad, swivel-eyed loons" to defect to his party.
Tory activists have attacked David Cameron's support for gay marriage, claiming it had made winning the next general election "virtually possible".
In a letter to the Prime Minister, organised by Grassroots Conservative group, chairman Bob Woollard said:
The Prime Minister's bizarre drive to ram this legislation through Parliament, without any democratic mandate and without the support of party members has been a disaster and has driven thousands of voters to Ukip.
The marriage-based family is at the heart of Conservatism. This dilution and unraveling of marriage has demotivated many ordinary loyal Conservative Party members and has undermined their years of hard work for something they believed in. It makes winning the next election virtually impossible.
For the sake of our children they should also strengthen conventional marriage.
UKIP leader Nigel Farage returned to England today saying he would not be intimidated by the anger his visit to Scotland prompted.
He called the nationalist protesters who jostled him in Edinburgh yesterday "fascist scum" and hung up on a Scottish radio interview. The SNP say he's "lost the plot".
Political Correspondent Carl Dinnen reports:
UKIP leader Nigel Farage has spoken to ITV News about his altercation with angry protesters during a visit to Edinburgh yesterday.
Mr Farage describes those who heckled him as "a pretty angry mob" who were "absolutely vicious, racist and nasty about England and me."
First Minister Alex Salmond said: "If you have someone who actually said this morning in an interview - accused a BBC interviewer of showing the same, as he put it, hate towards him as people in Edinburgh yesterday, then you're dealing with someone who is outwith the context of normal politics.
"So, yes, we'll have our political debate and discourse in a proper way in Scotland. We can frankly do without UKIP, who dislike everybody and know absolutely nothing about Scotland."

Anyone who heard the interview with Nigel Farage on BBC this morning would have thought he has completely lost the plot.
UKIP leader Nigel Farage told BBC Radio Scotland's Good Morning Scotland programme:
The idea that UKIP is some kind of horrible, nasty, anti-immigrant, racist party is not something that was evident to the rest of the country, but of course that wasn't what it was all about.
It was a demonstration dressed up as being anti-racism but in fact in itself was deeply racist, with a total hatred of the English and a desire for Scotland to be independent from Westminster. I mean, my goodness me, if this is the face of Scottish nationalism it's a pretty ugly picture.
The anger, the snarling, the shouting, the swearing was all linked in to a desire for the Union Jack to be burnt and extinguished from Scotland forever. There's absolutely no doubt who these people were or what they stood for.

Staff were forced to clear the Canons' Gait pub on Edinburgh's Royal Mile, where Mr Farage was due to hold a press conference near the Scottish Parliament, after it was filled with the chanting protesters.
The UKIP leader attempted to make an escape by taxi but protesters blocked its path and Mr Farage was forced to return to the pub, where police barricaded the doors against protesters until officers in a riot van came to his aid.
Two men were arrested after the protest and Mr Farage was escorted from the scene "to ensure his safety", Police Scotland said.
Mr Farage was in Edinburgh to promote his candidate Otto Inglis in the Aberdeen Donside by-election, but the pub was soon filled by dozens of protesters shouting "racist Nazi scum".
He told BBC Radio Scotland's Good Morning Scotland: "The fact that 50 yobbo, fascist scum turn up and aren't prepared to listen to debate I absolutely refuse to believe is representative of Scottish public opinion. It is not."
UKIP leader Nigel Farage has hung up the telephone during a radio interview with BBC Radio Scotland's Good Morning Scotland, according to reports.
Two people have been arrested after protesters demonstrated against the UKIP leader Nigel Farage at a pub in Edinburgh.
Police Scotland would not comment on what they had been arrested for.
