Nick Clegg will be handed a knighthood in the New Year’s Honours.

The former Liberal Democrat leader will become ‘Sir Nick’ when the full list is published on Saturday, senior party sources revealed.

The gong is in recognition of his five years as David Cameron’s deputy prime minister.

But the knighthood is likely to be controversial given that Mr Clegg is an arch Remainer and that his party has been showered with honours in recent years.

The Lib Dems have more than 100 representatives in the House of Lords despite their limited electoral success.

Will Miriam use a title? Miriam Gonzalez Durantez is unlikely to take up the title Lady Clegg after her husband is knighted. The Spanish lawyer does not use her married name and has never become a British citizen, raising further doubts about the title. It is uncertain whether the rules allow a non-British citizen to call themselves ‘Lady’. Foreigners who are given a knighthood cannot call themselves ‘Sir’ or ‘Dame’ – but it is unclear whether this restriction applies to spouses as well. At her international legal firm Dechert, she is known as Ms Gonzalez Durantez. Advertisement

Their peers will have considerable power over the course of the UK’s departure from the EU and Mr Clegg has called for a second referendum and written a book called How to Stop Brexit.

Senior Lib Dem figures to have received knighthoods include party leader Vince Cable and home affairs spokesman Ed Davey.

They were knighted after serving in the coalition government’s Cabinet. Both lost their south-west London seats at the 2015 election but returned to Parliament after winning again at this summer’s poll.

Another former Lib Dem Cabinet minister, Danny Alexander, was given a knighthood after losing his Scottish seat in 2015, although he has not returned as an MP. Former pensions minister Steve Webb was knighted a year ago.

Mr Clegg, who lost his Sheffield Hallam seat in June, had to wait longer. It is likely that – as with his former colleagues – his honour was delayed until after he left the Commons.

In his book on Brexit, Mr Clegg wrote: ‘There is nothing remotely inevitable about Brexit – except that it will be deeply damaging if it happens.’

The former Lib Dem leader sparked further fury among Eurosceptics when he travelled to Brussels to meet EU chief negotiator Michel Barnier.

He and two other Remain supporters, veteran Tory Ken Clarke, and Labour peer Lord Adonis, were accused of trying to interfere in Brexit talks.

Mr Clegg has called for Britain to hold a second referendum on the final Brexit deal agreed with Brussels. In September, he said there should be a second vote because the people who voted Leave were dying off.

He said the ‘high point’ of support had passed because ‘the oldest voters voted for Brexit in the largest numbers’.

Mr Clegg said MPs were ‘duty bound’ to reject any Brexit deal if it was not good enough. He said he supported Britain joining an ‘outer orbit of membership within a reformed European Union’.

Mr Clegg entered the Commons in 2005 after years working in Brussels. He took up a post with the European Commission in 1994 and five years later he was elected as a Liberal Democrat MEP in the European Parliament.

After swapping Brussels for Westminster, he won the race to become party leader in 2007 by beating Chris Huhne after Menzies Campbell was persuaded to step down.

Three years later he rode a wave of so-called ‘Cleggmania’ that briefly saw his party top the polls during the 2010 election campaign.

Although the results did not match this early success, he became a power broker during coalition talks, eventually siding with the Tories and allowing David Cameron to enter No 10.

In return, Mr Clegg was handed the position of deputy prime minister and brought the first Liberal MPs into government for decades. However, his party’s poll ratings began to plummet after he was forced to renege on a major pledge not to increase tuition fees.

And he suffered the humiliation of losing a referendum on changing the voting system to a form of proportional representation.

After the party’s 2015 election disaster, Mr Clegg resigned as leader and returned to the backbenches.

A year later, following the EU referendum, he became the party’s Brexit spokesman.

The honours system has come under attack in recent years over claims it is used to give gongs to political cronies. The honours will be announced formally on the night of December 29.

A Liberal Democrat spokesman said: ‘We don’t comment on any honours list speculation.’
