Konta will lead underdogs GB's promotion charge in the Fed Cup
Johanna Konta will lead Great Britain's bid to qualify for World Group II in their Fed Cup play-off against Romania next weekend.
Britain have not competed at world level in the competition since 1993 but go into the tie on clay at Constanta's Tennis Club IDU as heavy underdogs.
Much will rely on Konta, who is at a career-high ranking of seven after winning the biggest title of her career in Miami earlier this month.
She is joined in the team by Heather Watson, Laura Robson and doubles specialist Jocelyn Rae, while 18-year-old Katie Swan will also travel to the Black Sea coast.
Watson has had a difficult season and is ranked down at 110 but has an excellent record in the Fed Cup, having won 25 rubbers in singles and doubles and lost only seven.
The 24-year-old was unbeaten as Britain booked their place in the play-offs for the third time in six years by coming through the notoriously difficult Europe/Africa Zone Group in February.
