The Green Party has responded to Labour's controversial 'Controls on immigration' slogan mugs with a version of their own, bearing the words "Standing up for migrants".
The Labour Party was mocked by some Twitter users for its £5 Pledge 4 Mug and even the party's own former frontbencher Diane Abbot branded the move "shameful" and an "embarrassment".
Shadow business secretary Chuka Umunna insisted Labour was not using "dog whistle" tactics over the immigration election merchandise.
But Green Party Leader Natalie Bennett accused Labour of "pandering to Ukip" with the mugs, as she launched her party's rival design:
However, the party did clarify on its website that its £5 mug was "Exact design TBC" as it tweeted what appeared to be a mock-up.
The all-important podium plan for Thursday's night's general election debate on ITV has been announced.
Prime Minister and the Green Party's Natalie Bennett have been allocated spots at either end of the line-up of party leaders.
Ukip leader Nigel Farage is set to be sandwiched between Deputy Prime Minister Nick Clegg and Labour leader Ed Miliband.
Green Party leader Natalie Bennett has appealed for the support of voters "sick of business-as-usual politics".
Kicking off formal campaigning, she claimed the Greens are the "only party" offering economic changes that work for "everyone, not just those at the top."
Natalie Bennett hailed the Greens as "the politics of the future" at the party's conference in Liverpool today.
But the latest ITV News Index poll found just 9% of voters consider them a serious party.
ITV News' Political Correspondent Lewis Vaughan Jones reports:
Social care for all over 65s would be free under the Green Party, leader Natalie Bennett has announced.
In a speech to the party's spring conference in Liverpool, Bennett said the policy would become a manifesto pledge because it was vital in a "decent, humane" society.
A vote for the Greens would be a vote for "hope not fear"', she told the audience.
"This election can be a turning point in history. The moment where we can deliver a better Britain, a Britain which works for its people. A Britain which cares," she said.
The Green Party is most likely to be associated by the British public as "idealistic" and "amateurish", according to the latest ITV News Index poll.
The survey of 2,013 British adults suggests just 9% associated the Greens with the phrase "a serious party of Government".
The ITV News Index poll was carried out by ComRes between 27 February and 1 March.
The Green Party said David Cameron has shown "contempt" for the electorate after he issued a "final offer" to broadcasters over the TV leaders' debates.
A spokesman for the Greens said: "Not only is Cameron's announcement cowardly but it also shows his contempt for the electorate.
"People want to see a set of debates between all major party leaders, yet the Prime Minister is clearly scared of scrutiny."
The leader of the Green party has stated that supporting or joining terrorist groups like Islamic State and Al-Qaida should not be a crime.
Speaking on BBC's Daily Politics show, Natalie Bennett said that people should be free to think what they want and support who they want, though warned that anyone inciting or committing acts of violence would still feel the "full extent of the law".
"What we want to do is make sure we are not punishing people for what they think or what they believe," she said.
Bennett also spoke about plans to reduce the army - replacing it with a smaller home defence force.
She added that the Greens would progressively ease immigration controls.
"What we have to do is stop the race to the bottom on immigration rhetoric that we have been hearing, led by Ukip and sadly followed by the other [parties]," she said.
Green Party leader Natalie Bennett has welcomed reports her party will be included in the election debates hosted by ITV and the BBC.
She said the broadcasters have "joined the the age of multi-party politics".
