STORY: In the Scottish port of Peterhead, disillusionment with mainstream politicians is pushing a surge for Nigel Farage's populist Reform party.

Ahead of local elections this Thursday, Reform has promised to maximize oil and gas production in the North Sea and restrict the access of European fishing boats as well as curb immigration, its divisive core pledge.

Some see Reform as the best chance to revive Peterhead's fortunes.

"The government that's in at the moment isn't doing much," says Ian Baird, and nor has the Scottish National Party. "I'd recommend Farage and Reform, a change." 

As Labour hemorrhages support in its traditional leftist strongholds, Scotland and Wales have become fertile ground for Reform's promises to uproot old political systems and so-called liberal elites - and crack down on immigration.

Among Reform's most scandal-ridden problems has been its vetting of candidates.

Several Reform candidates have resigned over racism charges, one in Wales after images emerged of him making a Nazi salute.

Llyr Powell is the Reform candidate in Caerphilly, Wales.

"The vetting process has gone on come on leaps and bounds. There are difficulties in terms you don't, you can't vet for something someone here hasn't done yet. Or if someone's not completely transparent with you in that process."

Reform's post-Brexit rise has been mostly in England.

Now polls show Farage's party looks likely to become the official opposition to the Scottish National Party and Wales' Plaid Cymru.

But the SNP and Plaid say allegations of Reform racism are also sending voters their way.

Delyth Jewell, Plaid deputy leader, says she's lost count of those who've said they never voted Plaid - until now.

"But they have resented the vitriol, the nasty rhetoric that has been brought in by Reform to our streets and they want to do anything they can to oppose that. So in lots of ways, I think that the leader of Reform, he unifies so many people in being against his nasty vision for the future of the UK." 

In Caerphilly, Wayne Hunt says Reform seems locally popular.

"When I drink in the Workman's Club in (inaudible) back on a Sunday morning, all the boys, they're all backing Reform. I won't vote for them because they're ex-Tories and ex-Labour. I personally vote Plaid Cymru."
