Tories face a backlash after an online ad hailed bingo and beer tax cuts as "helping hardworking people do more of the things they enjoy".
The Scottish Parliament could gain more power over tax if voters reject independence, David Cameron has suggested.
MP Peter Bone insists he is "totally innocent" of allegations of benefit fraud, after his home was raided by police.
Nick Clegg has described the Conservatives' online Budget advert as "silly" but denied that George Osborne's statement marked a "Budget for plebs".
"It was a coalition budget through and through," the deputy prime minister told a caller on his regular LBC radio phone-in.
"I am really very proud of all of it," he added.
There is no question of the Conservatives' 'patronising' online Budget advert being pulled, a senior source has said.
The source said it could not be withdrawn as it was not part of a wider campaign involving other media such as TV and radio.
But they added: "We are quite proud of those tax cuts... We stand by what was said in that advert."
George Osborne said Labour was only attacking the Conservatives' Bingo duty advert "because they don't have anything else to say about the economy."
The Chancellor told Daybreak he was "proud" the budget was helping with tax on Bingo so the halls could stay open.
The "patronising" advert tweeted by Conservative party chairman Grant Shapps is "quite a small issue" when compared to the rest of the budget, according to a Lib Dem minister.
David Laws told Daybreak: "It's not something that I worry about tremendously - how the Conservatives chose to present things in the Chancellor's budget.
"I'm far more concerned about the big fundamentals here. The big fundamentals are firstly that we are getting recovery back and borrowing down."
Labour MP Jon Ashworth hit out at the "beer and bingo" online advert tweeted from Tory party chairman Grant Shapps, saying it shows how out of touch the government is.
This patronising advert shows again how out of touch David Cameron's Government is.
The Tory mask has slipped and revealed a party stuck in the past and only comfortable standing up for the privileged few.
George Osborne's Liberal Democrat deputy in the Treasury joined the chorus of criticism against the Tory bingo advert tweeted by Grant Shapps, saying he thought it was "patronising".
Treasury Chief Secretary Danny Alexander told BBC2's Newsnight:
I thought it was a spoof at first, it's just pretty extraordinary.
It may be our Budget but it's their words, I think it's rather patronising.
Also I think it actually demeans some quite sensible things. There are good reasons to be supporting bingo, there are good reasons to be encouraging our pub sector to be stronger - that's the analysis behind those measures.
This language, well that's for Grant Shapps to justify.
Twitter users have been sharing their thoughts on the Budget poster tweeted by Tory party chairman Grant Shapps, when he hailed the bingo and beer tax breaks as "helping hardworking people do more of the things they enjoy".

The Conservative Party chairman Grant Shapps has been criticised by Labour for tweeting a poster celebrating the cut in bingo tax and beer duty announced in today's Budget that "helps hardworking people do more of the things they enjoy."
Labour's media team has responded:
Dear Tories - what else do you think "they" do that you don't? #outoftouch
Baroness Warsi tells Tom Bradby on tonight's edition of The Agenda that she wants to see the Tories return to the "very core conservative principles" of allowing people to keep more of what they earn.
The Conservative peer said: "That means first of all focusing on the poorest first and making sure that they get the first bite of the cherry, but also looking at other people and looking at how we can bring the tax burden down. But we've got to balance that against the public finances."
The Agenda with Tom Bradby is on ITV tonight at 10.35pm.
Other guests on the show are TV historian Dan Snow, comedian Katy Brand, and columnist Jonathan Freedland.
