We've been tracking rumours that HTC isn't quite ready to launch its next flagship handset yet and with Mobile World Congress fast approaching, it's not going to make an appearance at the huge mobile trade show.

Rumours are now suggesting that the HTC One M10, codenamed HTC Perfume, will make an appearance at a London launch event on 11 April.

HTC has used London as a launch location previously: the HTC One M7 was launched in the UK capital with a parallel event in New York in 2013, so it's perhaps a plausible rumour.

The source is Portuguese website 4gnews.pt which has sourced this information from its own sources and so we have to take it with a pinch of salt as there's little to back this up.

But this new information does corroborate with some of the previous rumours that we've heard. The first of these was that HTC wasn't going to be launching a new flagship at MWC, having gone back to the drawing board with the design, so was looking at hosting its own launch event some weeks later. 

The second piece of information is that the HTC phone isn't going to carry the M10 name. We've been using HTC One M10 while we wait to learn the launch name of the handset that's codenamed Perfume. 

However, in the early days of rumours of this phone, one fairly reliable source said that it wasn't going to be called the M10 when it launches.

Recently we've seen a lot more information on HTC's handset: this potential launch date could be an important part of the puzzle.
