The senior Tory said Nigel Farage is 'not my cup of tea' and would question whether she was 'happy to serve' with the Ukip leader.

Scroll down for video . Education Secretary Nicky Morgan signalled she would quit the Cabinet if the Tories entered a power-sharing deal with Ukip . Mr Farage sparked controversy last week when he used a televised leaders' debate to target people with HIV coming to Britain. The Ukip leader was greeted with silence in the hall when he said during the debate about the NHS that of the 7,000 diagnosed with HIV, 60 per cent were born abroad. After saying this was something the other leaders would be 'mortified that I dare to even talk about it', he said: 'You can come to Britain from anywhere in the world and get diagnosed with HIV and get the retroviral drugs that cost up to £25,000 per year per patient. 'I know there are some horrible things happening in many parts of the world, but what we need is to put the National Health Service there for the British people and families who have paid into this system for decades.' It later emerged the comments were pre-planned in what Ukip insiders called a 'shock and awful' strategy. In an interview with The Times, Mrs Morgan condemned the remarks. She said: 'To say that in a calculated way to appeal to your core vote is pretty stomach-turning.' She added it is a 'legitimate question' to ask senior Tories about the make-up of future coalitions, if as the polls suggest no party gets an overall majority. Ukip leader Nigel Farage, who spent today on a boat in Grimsby with reality TV star Joey Essex, has said he is not seeking ministerial office in a coalition. But Mrs Morgan suggested she would not be willing to sit around the Cabinet table with Ukip: 'I can give you the answer which is that we are not talking about anything but a majority government. 'But I think if we end up in coalition discussion territory people will have to ask themselves who they are happy to serve with. 'It is difficult envisaging what might happen but Nigel Farage is not my cup of tea.' Mr Farage, who spent today on a boat in Grimsby with reality TV star Joey Essex, has said he is not seeking ministerial office in a coalition. But he would demand a referendum on Britain leaving the EU as the price for Ukip MPs supporting a Tory minority government. However, recent polls have suggested support for Ukip is slipping and Mr Farage might struggle to win his own seat in South Thanet. Mr Farage yesterday admitted Ukip has 'slipped back a bit' in the polls as the sense of euphoria among the party's supporters has waned. The Ukip leader has seen support for his party drop from 16.75 per cent in November to just 12.25 per cent today, with voters appearing to switch to the Tories in the run up to the election. Mr Farage is also facing a fight to win his own election battle after falling behind the Tories in Thanet South, Kent - despite enjoying a 12 point lead over his Conservative rival just two months ago. Speaking on a tour of the Midlands, he added: 'We are exactly where we were last August, having won the European elections - we were on 14-and-a-bit per cent. 'We won the European elections, we found that level and we did have a rally in the Autumn through the remarkable events of first Clacton and then perhaps more remarkably the Rochester by-election . 'We've slipped back a bit since then, there are 30 days to go and I think the issues Ukip is campaigning on are back in play.' David Cameron has urged Ukip supporters to 'come home' to the Conservatives, but has stopped short of ruling out having to rely on the Eurosceptic party if he falls short of a majority . Mrs Morgan is the only senior Tory minister defending a marginal seat, in Loughborough. Elected in 2010, with a majority of 3,744, Mrs Morgan became a Treasury minister in 2013 before being promoted to the Cabinet in July last year. Her rejection of the idea of power-sharing with Ukip comes after weeks of contradictory statements from senior Conservatives. In January, Tory party chairman Grant Shapps insisted his party would not enter a deal with Mr Farage. He said: 'I can rule [it] out, we are not going to do pacts and deal with Ukip, we are looking for an overall majority.' But Mr Cameron has only said that he is pushing for a majority, telling MailOnline in February: 'I'm not going to speculate about any outcome other than victory.' On Tuesday he issued a plea to those who had left the Tory fold: 'Look, we've heard the message loud and clear about the things you want to see changed and we'll change those things. Come with us, come back home to us, rather than risk all of this good work being undone.'
