Northern Ireland (Executive Formation etc.) Bill

I am most grateful to the noble Baroness for giving way; I am just following her argument, which is that the powers of a Prime Minister to prorogue Parliament should be limited because it might result in a no-deal Brexit. Why would she not extend that to the powers of a Prime Minister to call a general election? If a general election were called which lasted three weeks and 31 October was within it, we would have left the European Union. Is she not on very thin ice here?
