John Lloyd has resigned as Britain's Davis Cup captain after the team lost to Lithuania this month, dropping to the next-to-last level of the competition.
The Lawn Tennis Association also announced Wednesday that American Paul Annacone would no longer be Britain's Davis Cup coach. Instead, he will become the head coach of men's tennis.
Britain, playing without Andy Murray, lost 3-2 in Vilnius on March 7 to a country with only three players ranked in the top 1,000.
Britain must defeat Turkey in July to avoid falling into the bottom tier.
