Ukip's current advertising campaign has spawned a slew of imitations, one uses the Tories' 2005 campaign slogan "Are you thinking what we're thinking?" and even the departure of David Moyes gets a mention.Here are some of the imitations the ads have inspired.
Ukip has denied that the adverts are racist and said the criticism was designed to shut down the debate. Leader Nigel Farage said: "This, emphatically, is not a racist party."
Nigel Farage has continued to defend a controversial £1.5m advertising campaign which has been branded racist by opponents.
Opponents have labelled the eurosceptic party's new billboard campaign 'racist', a charge Nigel Farage claims is a 'classic trick'.
