Pompey have completed the signing of 25-year-old defender Connor Ogilvie.
He has put pen to paper on a two-year-deal – with the club option of a further 12 months – after leaving Gillingham at the end of last season.
Blues boss Danny Cowley said: “Connor is someone who’s been a really consistent performer at League One level for a number of years.
“He’s won Player of the Season awards for Gillingham and was a key member of their side after coming through at Tottenham.
“Being able to play as a left-back or a left-sided centre-half offers us versatility and also real competition for places, which is crucial in a 46-game season.
"Connor is someone who’s been a really consistent performer at League One level for a number of years."
“Connor has got a lovely range of passing and good technical attributes, while he’ll weigh in with goals as well.
“He’s got the qualities that Pompey fans will like to see – he’s brave and willing to put his head in where it hurts.
“That physicality will be a really big asset for us and so we’re delighted to bring Connor into the club.”
Ogilvie progressed through the ranks at Tottenham and gained first team experience with loan spells at Stevenage and Gillingham.
He joined the latter club on a permanent deal in the summer of 2019 and was named Player of the Year at the end of his first season.
The former England U17 international made a total of 171 appearances for the Gills, scoring 10 goals.
