Mr. Paul McDonald:

The UK determined early in the process that the development at Hinkley Point was not going to lead to a significant transboundary impact. The UK is maintaining that position to this day. The letter referred to by the Acting Chairman and subsequent letters sent by the UK refer to the "spirit" of what had transpired. One of the later letters, which was sent on 28 July 2017, stated:

As you are aware, the United Kingdom maintains that it did not breach the Espoo Convention in respect of the initial planning process for Hinkley Point C, but recognise the value of constructive engagement and it is in this spirit we are sending this letter.

In the July letter and in a letter sent the previous December, the UK was maintaining its position that it did not consider that it was in breach of the Espoo Convention.
