Plans for hundreds of redundancies at the Environment Agency have been put on hold as a result of the ongoing floods crisis sweeping the country.
The agency's chief executive has sent an email to staff saying that response to the flooding is taking priority over other work.
David Cameron has told ITV News Deputy Political Editor Chris Ship that the agency must ensure any redundancies "have absolutely no impact" on floods defences.
Paul Leinster said: "We are quite rightly prioritising incident response above all other work. With this in mind, we are reviewing the timetable for the change programme. We will not be taking further decisions on work stream proposals or structures whilst we remain in incident mode."

Mr Leinster added that once the emergency response was over, efforts to implement a successful change programme" would continue.
Mr Cameron refused to comment on the situation at the agency when asked by Labour leader Ed Miliband during Prime Minister's Questions earlier this week.
