The Bank of England is expected to keep interest rates unchanged on Thursday in its first meeting since Boris Johnson's election victory, despite growth flat-lining in Britain's Brexit-battered economy.

Economists predict the Bank's Monetary Policy Committee (MPC) will vote to keep rates at 0.75% in the noon decision.

Howevere it is likely two of the nine members will repeat their call for a cut to 0.5% after Jonathan Haskel and Michael Saunders dissented in November - which marked the first split decision on the MPC for more than a year.

The decision comes as recent official figures revealed the economy stagnated in October as Brexit and political uncertainty hampered activity, with more recent surveys confirming a worsening picture for growth.

Since then, the Conservatives' triumph in the December 12 election has helped remove some of the clouds of political uncertainty and concerns over another Brexit deadline extension.

However, fears over a no-deal Brexit remain at the fore, with Mr Johnson legislating to prevent MPs from extending the Brexit transition period beyond the end of 2020.
