Ipswich have signed Burnley defender Dara O'Shea for an initial £12m plus a potential £3m in add-ons.
The Republic of Ireland international has penned a five-year deal with the Tractor Boys.
He is Ipswich boss Kieran McKenna's 11th signing of the summer, following the capture of winger Jack Clarke from Sunderland on Saturday.
He is also the second Burnley player to join the club this summer after goalkeeper Arijanet Muric.
"It was really hard not to pay attention to everything the team was able to achieve last season and to have the chance to join a club with such ambition and momentum was really attractive," O'Shea said.
