Posted on another thread, but relevant here too.
The Sunday Times has today called for a tactical Leave vote to allow Cameron to renegotiate the terms of our membership with the EU, suggesting an emergency brake on immigration is reasonable.
On Thursday, therefore, we should vote “leave”. Y.[/QUOTE
Seriously, if you think we can vote 'leave' then go back and renegociate our terms and remain, you are going to have a nasty surprise. If the outcome is leave, how well do you think if will go down if Cameron says 'NO! I am going back to Brussels to negociate a New Deal. Wish me well'. He would be thrown in the sea. If you vote leave and this is the outcome, we will leave.
I didn't write it! But I do think a close result will resolve nothing and in that case a second referendum may be required.
