The Prime Minister visited MBDA's missile factory after launching her manifesto in Yorkshire
After a tour of the factory and meeting apprentices the PM sat down with Tower FM
Speaking about the North Mrs May said
"Infrastructure investment is an important element of ensuring growth in the economy and of course we have created the metro mayor that Andy Burnham now is and he has opportunities with the funding he has available with the power he has available in this Greater Manchester area"
It's the second time the PM has visited Bolton in recent weeks after launching her election campaign in the town.
"There is a very clear choice for people across Greater Manchester area when they come to vote it's not who they have voted for before it's who they want to lead the country and it's going to be me or Jeremy Corbyn"
