THE first complainant in the sexual assault trial of former Conservative MP Charlie Elphicke has been called to give evidence.

The woman, who was in her 30s at the time of the alleged assault in Elphicke's home in 2007, appeared via videolink and cannot be identified for legal reasons.

Opening the case yesterday, prosecutor Eloise Marshall QC described how the woman was "flattered" to be invited for a drink at Elphicke's home while his wife Natalie Elphicke was away.

The prosecutor said Elphicke sexually assaulted the woman and then chanted "I'm a naughty Tory, I'm a naughty Tory" in a "sing-song" manner as he chased her around the kitchen.

Elphicke, Dover MP from 2010 until 2019 when he stood down and was succeeded by his wife, denies three counts of sexual assault against two victims, in 2007 and 2016.

The trial at Southwark Crown Court is listed to last for four weeks.

The woman broke down while recalling the alleged assault by Charlie Elphicke.

She said Elphicke's wife was away "on a business trip" at the time, meaning the then-Dover MP was left with his two young children.

She said the assault occurred "quite late" in the evening, at about 9pm or 10pm.

The trial continues.
