Pictures, apparently showing the new Nokia Lumia 920 and 820 handsets, were released on Twitter on an account called @evleaks.
The pictures show the handsets, which look similar to Nokia's earlier Lumia models, in a range of colours, including yellow and red.

According to the paper, the larger of the two, the Lumia 920, has a 4.5-inch display and the smaller Lumia 820 has a 4.3-inch display but comes in more colours.
Nokia and Microsoft are holding a joint event in New York on Wednesday, at which they are expected to announce the new Windows Phone 8 handsets.
