A prominent Conservative backbencher has slammed the draft agreement negotiated by David Cameron on the UK's relationship with Europe saying it is "not worth the paper it's written on".
In an article for Prospect Magazine, Liam Fox highlights the apparent failure to secure an outright four-year brake on EU migrant benefits - the blueprint published yesterday by European Council president Donald Tusk states "the limitation should be graduated".
The former defence secretary said: "It is clearer than ever before that the renegotiation will not achieve this for us."
Crucially, we are now told that there will be no treaty change before the referendum.
Without this, the reform package is not worth the paper it’s written on.
He ends by urging readers to vote to leave in the European referendum.
David Cameron is expected to warn that voting for a "Brexit" would result in refugee camps springing up across the south-east of England.
If voters chose to stay - whenever the referendum comes - the deal upon which that decision was reached may not be the final word.
As his tour of Europe gets underway, David Cameron faces a fight to stop his proposed EU deal being watered down further.
