Peterborough have signed midfielder Michael Bostwick from Stevenage for an undisclosed fee.
Bostwick, who leaves Boro after almost 200 games for the club, has put pen to paper on a three-year deal at London Road.
The 24-year-old met up with his new team-mates in the departure lounge at Luton Airport on Monday morning as the squad flew out to Portugal for a pre-season training camp.
Bostwick has been an influential figure for Stevenage since joining the club in 2008 and helped Boro to back-to-back promotions into npower League One.
He is Peterborough's fourth summer signing following the arrival of Bobby Olejnik, Danny Swanson and Nathaniel Mendez-Laing.
