With news of #Twitter sacking 10% of their workers being confirmed, are they in trouble? Will the world be without Twitter? Have your say

Twitter has been overtaken in popularity recently by the likes of Instagram and Whatsapp, and it appears the firm may be struggling as a result. 

Chief executive Jack Dorsey has confirmed the company is 'parting ways' with 336 employees from across the company. 

The 38-year-old tweeted the news in which he described the decision to 'streamline' the company as 'extremely tough.'

Reports about company-wide layoffs were made by Re/code last week.  

Mr Dorsey was appointed permanent chief executive last Monday. 

In an email to staff, which was also sent to the US Securities and Exchange Commission, he said: 'We are moving forward with a restructuring of our workforce so we can put our company on a stronger path to grow. 

'The team has been working around the clock to produce streamlined roadmap for Twitter, Vine, and Periscope and they are shaping up to be strong.

'Product and Engineering are going to make the most significant structural changes to reflect our plan ahead. 

'We feel strongly that Engineering will move much faster with a smaller and nimbler team, while remaining the biggest percentage of our workforce. And the rest of the organization will be streamlined in parallel.

'So we have made an extremely tough decision: we plan to part ways with up to 336 people from across the company. We are doing this with the utmost respect for each and every person.
