Lady Starmer was accused of ‘crass insensitivity’ yesterday after wearing a freebie outfit to London Fashion Week while ‘Wardrobegate’ rages on.

It emerged this weekend that the Prime Minister’s wife was given high-end clothes from Labour donor Lord Alli as well as a personal shopper and garment alterations.

However, Sir Keir Starmer failed to declare the gifts on time – sparking ­outrage among MPs.

Yet, despite the scandal, Lady Starmer attended London Fashion Week yesterday in a loaned designer outfit.

The Conservatives said it was ‘shocking’ – while Labour MPs said they were ‘not impressed’ by the move after ten million pensioners were stripped of their winter fuel payments.

One Labour backbencher said: ‘MPs have no idea why the Prime Minister and his wife, or any MP, would need anyone else’s money to buy their own clothes. Or why they cannot see the crass insensitivity of the timing.’

Another Labour MP said it ‘sticks in your throat when people are really, really struggling’ amid the cost of living crisis. ‘It’s the inequality which it highlights. It looks like there is hypocrisy when the person who is in charge of policy decisions that are going to impact the very poorest [takes freebies],’ they added.

Despite calls for an investigation, sources said last night that the parliamentary standards commissioner will not look into Sir Keir’s alleged rule breach for his late declaration of the gift.

The Tories said the decision was ‘disappointing’ because ‘there hasn’t just been one incident where Starmer has made a mistake – it is clear this is a pattern of behaviour’.

A Conservative source said if the PM does not offer up a ‘fulsome apology’, it will be clear there is ‘one rule for Keir and another one for everyone else’.

It is understood Lady Starmer has received around £5,000 of high-end clothes from Lord Alli, who was already at the centre of a No 10 access scandal.

In a row dubbed ‘passes for glasses’, it emerged the former TV mogul gave Sir Keir thousands of pounds of suits and spectacles before being handed a rare Downing Street security pass .

But Lady Starmer appeared undeterred by the latest row yesterday morning, wearing a polka dot Edeline Lee two-piece and navy jacket to the brand’s fashion week show.

Both items were loaned to her by the brand, it was confirmed. The blouse and trousers are likely to be worth more than £1,000, while the jacket retails for £1,200.

A Tory source said: ‘It’s shocking that Lady Starmer thought it acceptable to strut her way through London Fashion Week adorned in free designer swag the day after it was revealed Keir Starmer had failed to declare donations for clothing gifted to his wife. While Starmer drives the country off the rails in his high-end suits, it’s people across the country who are paying the price.

‘If Keir Starmer truly believes in transparency and integrity in government as he waxes lyrical about, then he must urgently apologise to the public for having hidden these donations for months.’

Former Welsh Labour MP Beth Winter said she would be ‘putting in a request this week to Lord Alli to buy some nice warm coats to the many pensioners in Wales who can no longer afford to heat their homes’. 

Reform MP Richard Tice posted on social media: ‘Lovely outfits… What can pensioners afford? Who is donating their warm clothing?’

But a senior No 10 source said: ‘Vic isn’t seeking a public profile. She will support the PM at some official events but otherwise will be getting on with her life. How she spends her time is private.’ 

Sir Keir, who held talks with his Italian counterpart Giorgia Meloni in Rome yesterday, twice refused to rule out taking more clothes from Lord Alli.

He insisted there was a ‘massive difference between declarations and corruption’ and dismissed the idea that taxpayers should fund such expenses for prime ministers and their spouses.

But he suggested it would be ‘pushing it a bit far’ to deny him the right to accept certain kinds of hospitality. 

Giving the example of football tickets, which the Prime Minister is known to have accepted as gifts, he said: ‘I’m a massive Arsenal fan. I can’t go into the stands because of security reasons. Therefore, if I don’t accept a gift of hospitality, I can’t go to a game. You could say, ‘well, bad luck’. That’s why gifts have to be registered.

‘But, you know, never going to an Arsenal game again because I can’t accept hospitality is pushing it a bit far.’

The Sunday Times reported the donations from Lord Alli covered the cost of a personal shopper, clothes and garment alterations for Lady Starmer both before and after Labour’s election win.

MPs are required to register gifts and donations within 28 days.

Foreign Secretary David Lammy later sparked ridicule after suggesting there is no budget in the UK for prime ministers’ clothes and they must ‘look their best’ for the country.
