Dwain Chambers has been named in the Great Britain and Northern Ireland team for next week's European Cup in Malaga following his return from suspension.
Chambers will compete in the 100m and the 4x100m relay
Chambers, who was banned for two years after a positive drugs test, will race in the 100m and 4x100m relay.
The 28-year-old returned to action in Gateshead earlier this month and came third in the 100m at the British Grand Prix with a time of 10.07 seconds.
It will be the first time he has worn a British vest since 2003.
On that occasion, he finished fourth at the World Championships - a performance later annulled when he failed the drugs test.
The Londoner tested positive for steroid THG (tetrahydrogestrinone) in August 2003 and was handed a two-year ban in February 2004.
He can win us points and we can use him and exploit this
UK Athletics performance director, Dave Collins
That ban means Chambers is banned from life from the Olympics, and UK Athletics performance director Dave Collins admitted he had been torn on whether to select him.
Collins, who wants the GB relay quartet to match the gold medal it won in Athens in 2004, said: "There was a dilemma about picking an athlete who is ineligible for the Olympic Games.
"It's a difficult one, securing results rather than the longer-term objective.
"We have to get a team that can train together and that can win together.
"He can win us points and we can use him and exploit this."
Chambers was cleared to race in Gateshead after agreeing a deal to repay the IAAF, athletics' governing body, and UK Athletics prize money won during the period he was taking drugs.
Chambers' time of 10.07 made him the 14th fastest man in the world this season but, more significantly, saw him rise to the top of the European standings.
The European Cup is a pointer to the European Championships in Sweden this August, where Chambers is the defending 100m champion.
Chambers said: "I am very appreciative for the faith shown in me by selectors and by the reception I received at Gateshead a couple of weeks ago.
"The chance to once again wear a GB vest and represent my country is one I'm thankful for.
"Now I have been given this second chance I am looking forward to Malaga and bringing home maximum points for the team and country."
However, the Malaga event also represents a good opportunity to blood some of the country's youngsters.
Team GB need to reassert their status in the event after the men were embarrassingly relegated from the elite level last year.
They are only competing in that category this season because the Malaga venue has room for nine teams not the original eight.
Sprinter Jason Gardener, who is fighting his way back to fitness after a lengthy back injury, has been named in the 4x100m relay alongside Chambers.
Germaine Mason will also makes his Great Britain debut in the high jump after successfully switching nationalities from Jamaica.
The women's team, returning to the top group after being relegated two years ago, will be without Paula Radcliffe.
She is recovering after an operation on her injured foot and expects to be back in action next month.
