The Chancellor of the Exchequer set out very clearly some weeks ago what the position on this was. That those funds will be continued to be met, provided they give value for money and meet the UK government's objectives. He talked about the length of the process as he knows once we trigger Article 50.
The treaty allows for a process that can take up to two years. Of course, how long within that process it does take depends on the progress of the negotiations that take place.
