FANS of McDonald’s will argue that their trademark fries are the best of the high street chains.

Now McD’s is upping the ante with a whole new fries experience.

The fast food chain is now offering sweet potato fries in Sweden and Norway – and fans are going wild for them.

One lucky Stockholm resident tweeted: "McDonalds sweet potato fries is everything. Thank God for McDonald's."

Another tweeted: “They had sweet potato fries at the McDonald’s in Sweden and I’m still thinking about it.”

The posts have prompted some serious food envy.

On behalf of all of you suffering a sweet potato craving, we contacted McDonald’s to ask when they will be coming to the UK – but we are yet to get a reply.

In the meantime, there was a glimmer of hope in a tweet sent from the McDonald's account, which seemed to suggest it was up to the manager of your local branch.

So now you all know what you have to do.
