Great Britain started their Fed Cup Group One campaign with a resounding 3-0 win over Bosnia in Eilat, Israel.
Anne Keothavong defeated Dea Herdzelas 6-4 6-2 in the first rubber before British number one Heather Watson claimed a 6-3 6-4 victory over Anita Husaric to set up a 2-0 lead.
Laura Robson and Johanna Konta then finished things off with a comprehensive 6-0 6-0 whitewash of duo Jelena Simic and Jasmina Kajtazovic as Britain completed a perfect start.
The Pool B games had been delayed after heavy rain on Wednesday but it did not disrupt Britain's preparations as they started off in the best possible style ahead of Friday's scheduled meeting with Portugal.
Watson, ranked 41 in the world, was satisfied to start with a win against Bosnia, arguably the weakest team in Group B, knowing that Portugal and Hungary will be far tougher opponents.
"I was a little nervous going out today, but I'm pleased to get the first win under my belt," Watson told fedcup.com. "It wasn't easy, I was in and out of the match as it was the first match, but I'm more settled in now."
Robson, who teamed up with Watson in the doubles last year, played alongside rookie Konta and recorded Britain's first Fed Cup double bagel - a match win without dropping a game - in 11 years.
After the match, Konta said on Twitter: "Super happy with how my Fed Cup career has started. Hopefully many more wins to come for us! #TeamGB."
Captain Judy Murray hailed the Australian-born 21-year-old's start to the tournament, saying: "It was great to be able to put her in on the first day and for her to get her first win.
"She played fantastically well today, it was a dream debut for her."
