The woman who set fire to the Premier Inn at Haverfordwest is due to be sentenced at Swansea crown court tomorrow (Friday).

Georgina Tranter, of Redstone Court, Narberth, has admitted arson while being reckless as to whether life would be endangered. A more serious charge of arson with intent to endanger life was dropped by the Crown Prosecution Service earlier this month.

Tranter, aged 26, will also be sentenced for taking a vehicle without the owner’s consent, failing to provide a specimen for analysis and driving without insurance to which she had already entered guilty pleas.

Tranter has been told by Judge Peter Heywood that she is bound to receive a jail sentence for the arson offence, the only question was how long it would be for.

Tranter, a chemistry graduate, continues to be held at Eastwood Park women’s prison near Bristol, where she has been since January.

An earlier court hearing was told that on January 17 Tranter had attended the Hunt Ball with her boyfriend and a friend. While there she had got drunk and snorted a gram of what she believed to be cocaine.

After the ball the couple went back to the Premier Inn where she was locked her out of her room. The hotel receptionist eventually called the police who drove Tranter to her mother’s address in Narberth.

They assumed that she would stay there; however, she then took the keys to her mother’s Peugeot and drove back to the Premier Inn.

More than 100 guests were evacuated from the hotel at around 6.30am on a Sunday morning after a fire on the exterior of a fire door was extinguished by a resident.
