Newcastle boss Chris Hughton made his first transfer window breakthrough on Wednesday night when he clinched a deal for Manchester United defender Danny Simpson.
The 23-year-old, who has spent the last three months on loan at St James' Park, has signed a three-year deal after the clubs agreed an undisclosed fee.
The news will come as a boost to Hughton, who has seen other major targets Jermaine Beckford and Matthew Kilgallon opt to stay with their current clubs, while Nottingham Forest have rejected the Magpies' bid for James Perch as "derisory".
Simpson has played a major role in Newcastle's rise to the top of the Coca-Cola Championship table, where they stand three points clear of second-placed Forest with a game in hand.
He has made 22 appearances and his retention has been one of Hughton's main priorities this month.
The manager told the club's official website, www.nufc.co.uk: "We're delighted to complete a permanent deal for Danny.
"He's a player who has been with us since the summer and has played a key role during the first half of the season.
"Danny is a very popular lad in the dressing room and he took no time at all to settle in.
"He was always a player we wanted to keep at the club and he was very keen to stay given how much he's enjoyed his time here."
