Mr. Damien McCallion:

This is a constant challenge at the moment. We have a secure supply and we are comfortable with what we have, beyond even the levels of testing that are there today. If a number of countries got a resurgence at the same time, however, in a global sense, there would still be challenges there. The market has obviously invested a lot in manufacturing to increase that. We have also looked at diversification across platforms to ensure we are not completely dependent on one or two platforms which could present problems then if such a situation arose globally.
