Martin Lewis makes fresh warning to everyone in their 20s but fans aren't convinced

Martin Lewis might be the country's number one money-saving expert, but his most recent advice has left a lot of fans unconvinced.

The public-appointed king of finances recently appeared on Good Morning Britain, where he appealed to people in their 20s over where they keep their savings.

Lewis urged young people to consider putting their hard-earned cash into investments instead of savings accounts, in order to yield significantly more money back in the long term.

While most would consider this helpful advice, viewers were immediately turned off when he mentioned investing up to £20,000 each tax year; a laughable sum for the majority of young people who are already struggling to save for house deposits amid the ever-increasing cost of living.

"Ultimately, if you're 22 and you're going to be investing money for 20 years, the very substantial probability is if you put it in a wide spread of global assets, putting it in the stock market will smack the pants off putting it in savings," he told viewers.

"So currently you can put £20,000 per tax year, it's a lot of money, £20,000 each tax year, into an individual savings account, and that can be £20,000 in cash that are savings, 20,000 in investments which are stocks and shares, or a combination of both."

A clip of the programme was shared on GMB's Instagram account, where viewers were quick to question which 20 year olds would have a spare £20,000 to invest.

"Great idea, luckily everyone in the UK has a spare £20k knocking around," one commented, while another added: "Young people are saving to buy a house, not locking money away for 20 years."

A third wrote: "Which planet do you live on? Normal people don’t have £20k to invest."

But before the financial guru takes all the blame, he was actually commenting on changes that were expected to be announced by the Chancellor of the Exchequer, Rachel Reeves, over how much can be deposited into a cash ISA.

"The overall limit, she has said, will stay at £20,000, but the strongly suggested rumour is that she's going to drop the amount that you can put into cash ISAs, into savings," Lewis explained.

"The reason for doing this, we're being told, is not to raise tax revenue, they're very strong on that, is to try and encourage more young people to invest for their future, which is actually a good thing that they should be doing."

Reeves was expected to announce plans to reduce the allowance for tax-free savings, however, these plans have now been shelved due to public backlash, the BBC reports.
