Premier Inn owner Whitbread has unveiled plans to return another £2 billion to investors following its Costa Coffee sale and slash costs by a further £220 million.

Whitbread said it also saw potential to double the Premier Inn hotel chain to more than 170,000 rooms, including at least 110,000 in the UK, as part of a strategy update to investors.

It currently has over 74,000 rooms in the UK.

Whitbread shares rose nearly three per cent as investors cheered plans to return cash from the mammoth £3.9bn sale of Costa to Coca-Cola.

The group's share buy-back plans mean it will be returning £2.5bn in total to investors, having already kicked off a £500m programme in January after the Costa sale.

Whitbread is already the biggest operator in the UK budget hotels market with Premier Inn, with an 11% of the 700,000 rooms currently on offer.
