The Minister for Housing has defended the decision by the Government to postpone the publication of a major plan for the housing sector for a number of weeks.

Darragh O'Brien also denied that there had been any resistance from Fine Gael ministers to the Housing for All document, which had been expected to be published next week, but has been rescheduled to late August or early September.

The postponement has been criticised by opposition parties including Sinn Féin, which said the Coalition had not yet finished the document despite being a year in office.

Minister O'Brien said there were a "small few elements" of the Government's plan that are yet to be completed.

Speaking on RTÉ's Today with Claire Byrne, Minister O'Brien said "no one is delaying the plan".

"It's important to get the plan right, and that we publish the best plan for our people."

He said the plan is a "few weeks away".

"For the sake of a few weeks we can get the best plan we can put together that's fully costed between now and 2025 and into 2030 that will show us a pathway forward on how we can deliver affordable homes for the many thousands of people who've been locked out of the housing market," he said.

Minister O'Brien said he and his colleagues will be working through August on the plan, which he described as "positive, it is real and it will work".

He said there has been "predictable criticism levelled" at him, and that he is "more than happy to take it".

Minister O’Brien said all three party leaders have been involved in the creation of the plan, as well as the sub-committee on Housing, Minister for Public Expenditure and Reform Michael McGrath and Minister for Finance Paschal Donohoe.

"Everyone has been brought along and they are fully supportive."

He said the targets set out in the plan "have to be ambitious but also realistic".

"I have no concern around targets", he said.

When asked whether there had been "push back" from Fine Gael, the minister replied that there had not been.

Tánaiste Leo Varadkar also strongly denied there had been any fighting at Cabinet among the Government parties on stalling the publication of the strategy.

Speaking in Galway today, he said all Government parties are behind the strategy and it is one of the most important documents they will produce.

"We have three years left and we have to make a major dent in the housing crisis and that remains our priority," he said.

He said they are carrying out a review of the National Development Plan first, into which billions of additional resources are being allocated to housing across various departments, and how it will be spent, and that review will take a number of weeks.

He denied there was any 'fighting at Cabinet' between the government parties on this issue, and said it was "certainly not correct" to say Fine Gael were pushing for publication of the plan to be delayed.

"We want to make sure we get it right, that every Government department contributes to it, and that any targets we set are ambitious and achievable" he said.

Minister for Overseas Development Colm Brophy said there is great cohesiveness within the Government on the Housing for All plan and that a very good plan will be delivered after taking a few extra days 'to get it right'.

Minister Brophy said the key thing is "getting this plan right to try and build and supply the housing that is required".

He said the plan will outlive any one election and it is key to provide the structures and way houses are built and delivered on a sustainable basis into the future.
