Avro was pitching the Arrow to the UK in a bit of desperation, I think, but the interest from the RAF was said to be quite high, especially given the familial linkage of Avro Canada to the original Avro. WWII was only still recent, and Avro Canada had joined in Lancaster bomber production back then, so there were optimistic visions of British sales.

You mentioned the TSR-2's role as a low-level nuclear interdictor - this same role was taken up by RCAF CF-104 Starfighters(!) stationed in Germany carrying U.S. made free fall nuclear bombs on planned routes into Poland and further.
