He achieved lower production prices by using injection moulding plastics for hi-fi turntable covers, severely undercutting competitors who used vacuum-forming processes.

[citation needed] In the mid 1970s manufacturing capacity was expanded to include the production of audio amplifiers, stereo cassette recording decks and AM/FM radio tuners.

Although the CPC range were attractive machines, with CP/M-capability and a good BASIC interpreter, it had to compete with its arch-rivals, the more graphically complex Commodore 64 and the popular Sinclair ZX Spectrum, not to mention the highly sophisticated BBC Micro.

In 1986, Amstrad bought the rights to the Sinclair computer product line and produced two more ZX Spectrum models in a similar style to their CPC machines.

The launch of a range of business PCs was marred by unreliable hard disks (supplied by Seagate), causing high levels of customer dissatisfaction and damaging Amstrad's reputation in the personal computer market, from which it never recovered.

[22] After a take-over battle with Robert Maxwell for ownership of Tottenham Hotspur, Sugar teamed up with the club's manager Terry Venables and bought it in June 1991.

Although his initial investment helped ease the financial troubles the club was suffering at the time, his treatment of Tottenham as a business venture and not a footballing one made him an unpopular figure among the Spurs fans.

"[24] In 1992, Sugar was the only representative of the then "big five" (Arsenal, Everton, Liverpool, Manchester United and Tottenham Hotspur) who voted in favour of Sky's bid for Premier League television rights.

[25] During negotiations, Sugar called Sky CEO Sam Chisholm and angrily ordered him to "blow [ITV] out of the water" with a much higher bid.

Because Spurs had not qualified for European competition, Klinsmann decided to invoke an opt-out clause in his contract and left for Bayern Munich in the summer of 1995.

The first was Peter Shreeves, who replaced Venables in 1991, followed by the dual management team of Doug Livermore and Ray Clemence in 1992, former Spurs midfielder Osvaldo Ardiles in 1993, and Gerry Francis in 1994.

[29] In February 2001, after speculation and confirmation on 11 December 2000, Sugar sold his majority stake at Tottenham to leisure group ENIC, selling 27% of the club for £22 million.

[32] Sugar later donated £3 million from the proceeds of the sale of his interests in Tottenham Hotspur to the refurbishment of the Hackney Empire in his native East End of London.

[33] Sugar became the host of the BBC reality show The Apprentice, which has had one series broadcast each year from 2005, in the same role as Donald Trump in the US version.

As a condition for appearing in the third series, Sugar placed a requirement that the show be more business-oriented rather than just entertainment and that he should be portrayed in a less harsh light, to counter his somewhat belligerent reputation.

Amsair operates a large Cessna fleet, and one Embraer Legacy 650 with the registration G-SUGA, offering business and executive jet charters.

[50] Sugar is Chairman of Amscreen, a company run by his son Simon, specialising in selling advertising space on digital signage screens that it provides to retailers, medical centres and leisure venues.

[56] In February 2009, the Evening Standard journalist Andrew Gilligan reported that Sugar had been approached to be the Labour candidate for Mayor of London in 2012.

[58] During Prime Minister Gordon Brown's cabinet reshuffle on 5 June 2009, the BBC reported that he would be given a life peerage and had been offered a job as the government's "Enterprise Champion".

[62] In 2011, Sugar donated a total of £69,000 to Labour or to leader Ed Miliband's office, but the following year he defied party rules to implore the public to not vote for its candidate for London Mayor, Ken Livingstone.

[63] In August 2014, Sugar was one of 200 public figures who were signatories to a letter to The Guardian expressing their hope that Scotland would vote to remain part of the United Kingdom in September's referendum on that issue.

He issued a statement to say: In the past year I found myself losing confidence in the party due to their negative business policies and general anti-enterprise concepts they were considering if they were elected.

[65]Before the 2016 London mayoral election, Sugar said that he is popular politically,[66] and repeatedly urged the public to not vote for the eventual winner, Labour candidate Sadiq Khan.

"[72] On 31 March 2018, after complaints from Labour politicians, Sugar deleted a tweet showing an edited image of Jeremy Corbyn in a car with Adolf Hitler.

During an attempted landing in his Cirrus at the grass airfield City Airport Manchester on 5 July 2008, he overshot the runway after touchdown due to poor weather and wet field conditions.

[84] The threats are alleged to have been made by Glen Jenvey, the source of the original story in The Sun, who posted to a Muslim website under a false identity.

[85] On 10 June 2020, he, a pilot since 1975, announced on Twitter that he was taking delivery of a new 2020 Cirrus SR22T single-engine aircraft from the United States where he owns a Florida home and multiple boats, including a refurbished one named Little Tub and a superyacht.

As a result, Sugar wrote a cheque for £186m payable to HMRC for tax owed on share dividends that he received from his company Amshold in 2021, amounting to £390m.

"[104] On 30 September 2013, Sugar tweeted a picture of Chinese child crying 'because he was told off for leaving production line of iPhone 5'.

[105][106] On 20 June 2018, he tweeted a picture of the Senegal national football team edited next to images of fake handbags and sunglasses, claiming that some of the players looked just like hawkers he had encountered in Marbella.
