Which means that BRexit would mean that EU would get rid of USA's strongest "lapdog".
Wrong. UKIP and Labour hold the majority seats for the UK in the EUP and they're both against TTIP.
How would that stop the UK government from pushing this? The EUP does not control the UK government or the House of Commons.
@deif TTIP will have to be ratified by the individual national governments, either by voting on it in parliament or through direct popular vote.
Well the UK government doesn't get a vote on TTIP... I mean it's a reason to not vote for a Brexit if anything since then they WOULD get a vote to secure a trade deal privately with the US if the UK left the EU.
But the Commission largely works on behalf of the Council of Ministers where the UK Government (Conservative) have the vote. Also if the UK leaves Europe the UK could sign up all on its own (although possibly on even worse terms).
