What is this big sign doing on Southsea seafront?

The letters, spelling out ‘It must be love’, were spotted on the edge of Castle Field near Southsea Castle.

Barriers have been placed around the large white lettering, while spotlights have been built on to the top of each letter.

It is thought that the letters appeared on the seafront overnight.

The mystery appearance has left some residents intrigued.

Wendy Smith, 44, and her son Harvey, 10, were perplexed by the letters.

Wendy, of North End, said: ‘I honestly haven’t got a clue what it could mean. Really, I don’t know.’

Harvey added: ‘It was a bit of a surprise to see it this morning. It’s come up out of nowhere.’

Vicki Hamlin, 53, of Portsmouth was walking her two dogs in Castle Field and felt the sign might have a romantic twist to it.

‘I really hope it’s about somebody proposing, that would be really cute,’ she said.

Teresa and Mark Gratton, of Copnor, had another theory.

The couple were out walking with their two grandchildren Cohen, five, and Arlo, one, in Castle Field.

Teresa said: ‘I was wondering what it could mean when we walked in. It could be something to do with Christmas.’

Mark added: ‘I think it looks like something to do with Victorious.’

Callum Knox, 19, of Southsea, added: ‘It’s definitely got to be something to do with Victorious. They had similar lettering up in the same place last year. So I’m sure it’s got to be this.’
