PORTISHEAD'S RNLI has received a whopping £1,260 lump sum from a mystery donor.

An envelop containing the cash, which was made up of twenty pound notes, was sent to the lifeboat station, where it was opened to the shock and surprise of crew members.

No note was included.

Lifeboat operations manager, Dave Slack, was wowed when he saw what had been posted. 

Dave said: "It’s a real privilege for us to receive kind letters of gratitude from our supporters as they always lift our spirits and make us smile.

"I knew this envelope was something a little different when I picked it up, but I was very surprised when saw the cash donation inside.

"I was even more taken aback when I counted the amount and realised how generous someone had been.

"There was no letter or note inside the envelope, so on behalf of myself and everyone in the Portishead crew, we want to say a huge thank you to our mystery donor.

"This money will go towards the kit that our crew need to continue to train, operate, and save lives.

"We hope that they will somehow see this message and know that we are extremely grateful."
