This International Investment Summit has been circled in the new government's diary from the day it took office as a key opportunity to set out its claim to be a new kind of centre-left administration.
Pro worker, as it's union funders and core voters take for granted; pro public-services, as the electorate that gave it a majority expects; but unashamedly pro business too.
It's a trio of ambitions that do not always sit happily together and are usually framed as in competition.

Labour say they are serious about changing a perception they know is shared by several of the overseas investors present.
