Tinie Tempah has postponed his December 2013 UK arena tour.

In a statement on his website, the rapper says that he was so focused on working on putting out his new second album 'Demonstration' that he's not had enough time to prepare for the shows.

"Guys, I only think it's right to tell you that after delivering 'Demonstration' and working flat out trying to make an album you guys would be proud of, I feel I haven’t had enough time to prepare for the December Tour to make it the best it can be," he wrote.?

He continued: "So myself and management have decided to postpone it until April so I have enough time to rehearse all the new songs and make this tour even better than the last one. Apologies to everyone who was looking forward to it April will be amazing. I promise. See you then!"

'Discovery', Tempah's follow-up to his 2010 debut 'Disc-Overy', was released on November 4 and features guest appearances from 2 Chainz, Big Sean, Labrinth, Laura Mvula and Emeli Sandé.
