GP2 will stay at a full compliment of 13 teams, 26 drivers on the grid when racing resumes in March in Malaysia, after series organisers confirmed that Dutch team MP Motorsport have signed up to compete in next year's championship battle.
"We are pleased to welcome MP Motorsport to GP2," said series CEO Bruno Michel. "I am convinced that they will adapt quickly to the series and to the car.
"It's always a big challenge for a new team to join our high levelled field, but the winter break will give them the time they need to get ready and be competitive straight from the first pre-season test session next year," he added.
MP Motorsport was launched in 1999, originally competing in European and Benelux Formula Ford before moving to Formula Renault 2.0 in 2003. Among the drivers to have competed under the MP Motorsport name are Ricardo van de Ende, Bas Lammers, Nigel Melker and Daniël de Jong.
De Jong - who competed in eight races in the 2012 GP2
season with Rapax - had been confirmed as MP Motorport's first driver signing for their new endeavour in GP2
MP Motorsport team principal Sander Dorsman said that he was "very happy to have Daniël onboard for our first season in GP2, we know him well."
The 20-year-old from Rotterdam made his series début in Valencia, and also competed at Silverstone, the Hungaroring and Spa-Francorchamps. De Jong spent all four of the post-season test sessions available to GP2
teams at Barcelona in October and Jerez
last week working with the outgoing Scuderia Coloni team.
Coloni opted to leave the GP2
Series at the end of the 2012 season after unspecified disagreements with the series organisers, leaving a vacancy on the grid that MP Motorsport will now fill.
"[Daniël] showed good speed and consistency during the post-season tests in Barcelona and Jerez," said Dorsman. "We aim to sign another experienced GP2
driver to maximise the performance of the team going forward.
