Listen, it's hard launching a new political party. There's a lot of stuff to remember and a to-do list the length of your arm.

But, if there's one thing that should be pretty high up on that list, it's claiming the .com domain.

Oops-a-daisy, looks like Nigel Farage forgot to complete this rather crucial step on his to-do list when he launched his new Brexit Party — a new Eurosceptic, pro-Leave political party.

Unfortunately for ex-UKIP leader Farage, a pro-Remain group has claimed the domain thebrexitparty.com, and it's using the site to send a message that deviates from the new party's manifesto.

Here's what you'll see if you go to the website:

Richard from Led By Donkeys the pro-Remain group behind the domain debacle told Mashable why the group chose to buy up the domain.

"When we saw he'd neglected to register the domain for his new party we thought we'd have a bit of fun," Richard continued. "But there's also a serious message. We need to vote in the European elections because every vote for another party is a vote against Farage."

At a launch event in Coventry, UK, Farage said the European elections are the "first step" for the new party. The UK is expected to hold European Parliament elections at the end of May after Prime Minister Theresa May obtained a Brexit delay until Oct. 31. European elections take place so voters in EU member states can elect MEPs, or Members of the European Parliament.

Looks like Farage might have found a workaround for his domain problem. Since the .com address is taken, the Brexit Party has opted for a .org URL.
