I absolutely agree. In January 2018, on Second Reading of the 2017-19 Bill, the then Secretary of State stood up and said that he would be looking for a new approval process and take soundings on that, but that has simply not happened. As things stand, there is no longer a parliamentary veto, and no formal scrutiny committee has yet been established, despite US negotiations having started.
The important point of a parliamentary veto is not that it is often used, but rather, as seen in other Parliaments, that it encourages the Executive to seek consensus on their negotiating mandate, and keeps legislators in touch during negotiations through regular discourse and discussion. A wise Executive will naturally wish to avoid an unnecessary bust-up just before signing an FTA. Of course, that is where it all went wrong with the TTIP negotiations between the US and the EU, because the US Congress and the EU Parliament were disclosing information to their respective elected representatives that was not provided to UK parliamentarians.
