Concerns are growing for the welfare of the missing niece of a Scottish politician. Rosie Johnson, 22, of Glasgow, has been missing on the Isle of Wight since last weekend.

She was last seen at the PGL Little Canada activity centre in Wootton, where she works, on Sunday evening. Police officers and volunteers from Isle of Wight search and rescue, Hampshire search and rescue and the coastguard spent Wednesday searching in and around Wootton Creek.

Her uncle Daniel Johnson, the Scottish Labour MSP for Edinburgh Southern, tweeted an appeal for help to find her.

She is described as being of slim build with mousy brown hair and was last seen wearing a dark blue padded jacket and trousers.

Insp Andy McDonald, of Hampshire Constabulary, said: “We have serious concerns for Rosie’s welfare. Information suggests she is still on the island so this is where we are focusing our search. However, we would ask anyone with any information about her whereabouts to contact us as soon as possible.

“I would like to repeat our request for members of the Wootton community and surrounding areas to check any sheds, outbuildings or boats. Please carry out a thorough search and call us on 101 if you think you see or find anything that could assist our search. Residents will notice a lot of activity in the area today while we carry out our inquiries. If they have any concerns, they are encouraged to come and talk to us.”

A PGL spokeswoman said: “A member of staff working at our Little Canada site on the Isle of Wight did not report for work as planned on Monday morning. We were unable to establish their location and as a precaution informed the police who are now coordinating a search. We are providing any support we can to help with this.”
