Judy Murray has resigned from her position as captain of the Great Britain Fed Cup team with immediate effect.
The 56-year-old took up the role in 2011, replacing Nigel Sears.
During that time she was unable to guide the squad through to the coveted World Group, but on two occasions they did progress beyond the Europe/Africa Zone Group II.
"I've loved the challenge of leading the team over the past five years, raising the profile of the event, our players and women's tennis in this country," Murray said in a statement.
"I would also like to take this opportunity to thank all the players, support staff and the fans for their commitment to the team over the years.
"It's a big regret for me that we didn't make it to the World Group, but what we have now is a pool of players capable of competing at that level. We just need them all to be available and fit to play at the same time."
The Lawn Tennis Association has confirmed that Murray's successor will be announced before the end of the year.
