er, my lord may i say that er in relation to the witness statement  erm, clearly the credibility of this, the plaintiff mr  is going to be substantially in issue er and therefore er i propose er not to simply to tell him  er and say erm in your witness statement your evidence  erm but clearly to take him to those areas which are in dispute and to ask him to deal fully with them in  i appreciate it's going to erm  take some time to do that but it is important in my submission that your lordship has the ability to er assess  the plaintiffs.
