British high-tech firm Dyson has moved 100 back office jobs to India and the Czech Republic in advance of the firm's decision to move its headquarters to Singapore.

The company, owned by Brexit-supporting businessman James Dyson, announced last month that he was pulling the company's headquarters out of Britain ahead of the country's departure from the European Union.

The decision to transfer the firm's headquarters to Singapore means it will no longer be a British registered company and the low-tax city state will become its tax base.

The Financial Times claimed the firm has also made more than 150 people redundant

The firm's chief executive Jim Rowan dismissed claims the decision to move to Singapore was due to Brexit or Singapore's low-tax regime.

He said: 'The move is nothing to do with Brexit or tax, it’s about making sure we are future proofed. There are huge revenue opportunities in Singapore, China is the poster child of that,' he said.

'The tax difference is negligible for us, we are taxed all over the world and we will continue to pay tax in the UK. We will continue to invest in the UK, in Malmesbury, in Bristol and London.'

However, according to the Financial Times, staff at the company's base in Malmesbury were warned in July that their jobs were at risk as a result of restructuring plans.

Some 150 people were made redundant with 100 of those roles outsourced to India. Several positions were moved to the Czech republic.

As part of the plan to move the company's headquarters, two senior executives will transfer to Singapore.

The company, best known for its vacuum cleaners and other domestic appliances, is working on developing an electric vehicle in the Asian nation.

The firm said in a statement: 'An increasing majority of Dyson’s customers and all of our manufacturing operations are now in Asia; this shift has been occurring for some time and will quicken as Dyson brings its electric vehicle to market.

'We are now at a point where Dyson’s corporate head office will relocate there to reflect the increasing importance of Asia to Dyson’s business.'

But having one of Britain’s most successful manufacturers quit the UK comes at a sensitive time, with several car makers including Nissan, Ford and Toyota warning about the rising prospects of a no-deal Brexit, which would jeopardise their operations in the country.

Dyson was keen to stress its commitment to Britain, pointing out that it is investing £200 million in new buildings and testing facilities at its campus at Hullavington Airfield.

The company bought the disused airfield two years ago and has already renovated two hangars at the 517-acre site.

The announcement was made alongside Dyson’s full year results for 2018, when profits topped £1 billion for the first time.

Turnover rocketed 28 per cent to £4.4 billion and profits jump 33 per cent to £1.1 billion, with Mr Rowan pointing to the success of products such as its Supersonic hairdryer.

A spokesman for Dyson told MailOnline: 'Dyson ended 2018 with more people in the UK than ever before and we continue to grow here.

'However, as a increasing proportion of our sales are outside the UK - currently 96 per cent - it is natural to reassess how we best support our global operations.

'We have restructured some roles with this in mind.'
