The Football Association's technical director Dan Ashworth is to leave his role to take up the same position at Premier League side Brighton.
Ashworth joined the FA in 2013 from West Brom and was in charge of the England's elite men's and women's teams as well as FA education and coaching.
Brighton said Ashworth, 47, is "is set to begin his role with Albion in the spring".
The FA confirmed that Ashworth "has resigned as technical director".
Ashworth had spells at Peterborough United and Cambridge United before being appointed at West Brom.
Last year, former FA former board member Dame Heather Rabbatts called Ashworth's position "untenable" after claims by Women in Football the FA did not carry out due diligence when Mark Sampson was appointed as England women's boss in 2013.
Ashworth helped appoint Sampson - who was sacked after evidence of "inappropriate and unacceptable" behaviour with female players in a previous role - in December 2013.
