One expert has voiced concerns ahead of the Finance Minister's announcement to improve competition in the grocery sector.

Nicola Willis is set to detail the next steps in the Government's moves to create more competition in the sector - and she's voiced support for a third player joining the market.

Grocery policy expert Ernie Newman explained why he's not feeling too confident this will lead to real change.

"I feel that we're in a generation of politicians who are much more focused on announcements without guns - call me a cynic if you like, but I'd love to be proved wrong."
